# # Configuration file for the cryptroot initramfs hook. # # # KEYFILE_PATTERN: ... # # The value of this variable is interpreted as a shell pattern. # Matching key files from the crypttab(5) are included in the initramfs # image. The associated devices can then be unlocked without manual # intervention. (For instance if /etc/crypttab lists two key files # /etc/keys/{root,swap}.key, you can set KEYFILE_PATTERN="/etc/keys/*.key" # to add them to the initrd.) # # If KEYFILE_PATTERN if null or unset (default) then no key file is # copied to the initramfs image. # # Note that the glob(7) is not expanded for crypttab(5) entries with a # 'keyscript=' option. In that case, the field is not treated as a file # name but given as argument to the keyscript. # # WARNING: # * If the initramfs image is to include private key material, you'll # want to create it with a restrictive umask in order to keep # non-privileged users at bay. For instance, set UMASK=0077 in # /etc/initramfs-tools/initramfs.conf # * If you use cryptsetup-suspend, private key material inside the # initramfs will be in memory during suspend period, defeating the # purpose of cryptsetup-suspend. # #KEYFILE_PATTERN= # # ASKPASS: [ y | n ] # # Whether to include the askpass binary to the initramfs image. askpass # is required for interactive passphrase prompts, and ASKPASS=y (the # default) is implied when the hook detects that same device needs to be # unlocked interactively (i.e., not via keyfile nor keyscript) at # initramfs stage. Setting ASKPASS=n also skips `cryptroot-unlock` # inclusion as it requires the askpass executable. #ASKPASS=y
