+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# NOTE: This is no more used for setting up users MAIL environment variable

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# Essentially:

+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for
+# login, su, etc.
+#
+# This is a temporary situation: setting these variables will soon
+# move to /etc/default/useradd and the variables will then be

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for
+# login, su, etc.
+#
+# This is a temporary situation: setting these variables will soon
+# move to /etc/default/useradd and the variables will then be

+# See #290803 and #298773 for details about how this could become a security

+# Enable logging of successful logins

+#
+# In Debian /usr/bin/bsd-write or similar programs are setgid tty
+# However, the default and recommended value for TTYPERM is still 0600

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:

+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for
+# login, su, etc.
+#
+# This is a temporary situation: setting these variables will soon
+# move to /etc/default/useradd and the variables will then be
+# no more supported
+MAIL_DIR /var/mail
+#MAIL_FILE .mail

+# Enable logging and display of /var/log/faillog login failure info.
+# This option conflicts with the pam_tally PAM module.

+# WARNING: Unknown usernames may become world readable.
+# See #290803 and #298773 for details about how this could become a security

+LOG_UNKFAIL_ENAB no
+
+#
+# Enable logging of successful logins
+#
+LOG_OK_LOGINS no
+
+#
+# Enable "syslog" logging of su activity - in addition to sulog file logging.
+# SYSLOG_SG_ENAB does the same for newgrp and sg.

+# In Debian /usr/bin/bsd-write or similar programs are setgid tty
+# However, the default and recommended value for TTYPERM is still 0600

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#
+# For discussion, see #314539 and #248150 as well as the thread starting at

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# NOTE: This is no more used for setting up users MAIL environment variable

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# Essentially:

+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+# In Debian /usr/bin/bsd-write or similar programs are setgid tty
+# However, the default and recommended value for TTYPERM is still 0600

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+#
+# NOTE: This is no more used for setting up users MAIL environment variable

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:

+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for
+# login, su, etc.
+#
+# This is a temporary situation: setting these variables will soon
+# move to /etc/default/useradd and the variables will then be

+#
+# In Debian /usr/bin/bsd-write or similar programs are setgid tty
+# However, the default and recommended value for TTYPERM is still 0600

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,

+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:

+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:

+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# /etc/pam.d/common-password - password-related modules common to all services
+#
+# This file is included from other service-specific PAM config files,
+# and should contain a list of modules that define the services to be
+# used to change user passwords. The default is pam_unix.
+
+# Explanation of pam_unix options:
+#
+# The "sha512" option enables salted SHA512 passwords. Without this option,
+# the default is Unix crypt. Prior releases used the option "md5".
+#
+# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
+# login.defs.
+#
+# See the pam_unix manpage for other options.
+
+# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
+# To take advantage of this, it is recommended that you configure any
+# local modules either before or after the default block, and use
+# pam-auth-update to manage selection of other modules. See
+# pam-auth-update(8) for details.
+
+# here are the per-package modules (the "Primary" block)
+password [success=1 default=ignore] pam_unix.so obscure sha512
+# here's the fallback if no module succeeds
+password requisite pam_deny.so
+# prime the stack with a positive return value if there isn't one already;
+# this avoids us returning an error just because nothing sets a success code
+# since the modules above will each just jump around
+password required pam_permit.so
+# and here are more per-package modules (the "Additional" block)
+# end of pam-auth-update config

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# KILLCHAR Terminal KILL character ('\025' = CTRL/U).
+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# At the same time, using shell rc to set umask won't catch entries which use

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use

+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#
+# For discussion, see #314539 and #248150 as well as the thread starting at

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for
+# login, su, etc.
+#
+# This is a temporary situation: setting these variables will soon
+# move to /etc/default/useradd and the variables will then be

+#
+# In Debian /usr/bin/bsd-write or similar programs are setgid tty
+# However, the default and recommended value for TTYPERM is still 0600

+# ERASECHAR Terminal ERASE character ('\010' = backspace).
+# KILLCHAR Terminal KILL character ('\025' = CTRL/U).
+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#
+# For discussion, see #314539 and #248150 as well as the thread starting at
+# http://lists.debian.org/debian-devel/2005/06/msg01598.html

+# Essentially:

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# See default PAM configuration files provided for

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:

+# - MAIL_FILE defines the location of the users mail spool files as the

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# At the same time, using shell rc to set umask won't catch entries which use

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.

+# This avoids the confusion created by having the umask set

+# UMASK usage is discouraged because it catches only some classes of user

+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"

+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.

+# Essentially:

+#
+# NOTE: This is no more used for setting up users MAIL environment variable

+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home

+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# Directory where mailboxes reside, _or_ name of file, relative to the

+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#

+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.

+# UMASK usage is discouraged because it catches only some classes of user

+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).

+# UMASK Default "umask" value.
+#
+# The ERASECHAR and KILLCHAR are used only on System V machines.
+#
+# UMASK usage is discouraged because it catches only some classes of user
+# entries to system, in fact only those made through login(1), while setting
+# umask in shell rc file will catch also logins through su, cron, ssh etc.
+#
+# At the same time, using shell rc to set umask won't catch entries which use
+# non-shell executables in place of login shell, like /usr/sbin/pppd for "ppp"
+# user and alike.
+#
+# Therefore the use of pam_umask is recommended (Debian package libpam-umask)
+# as the solution which catches all these cases on PAM-enabled systems.
+#
+# This avoids the confusion created by having the umask set
+# in two different places -- in login.defs and shell rc files (i.e.
+# /etc/profile).
+#
