+# 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).

+#
+# 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
+# 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
+# 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).
+#
