NAME

       systemd-cryptsetup-generator - Unit generator for /etc/crypttab

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-cryptsetup-generator

DESCRIPTION

       systemd-cryptsetup-generator is a generator that translates /etc/crypttab into native
       systemd units early at boot and when configuration of the system manager is reloaded. This
       will create systemd-cryptsetup@.service(8) units as necessary.

       systemd-cryptsetup-generator implements the generator specification[1].

KERNEL COMMAND LINE

       systemd-cryptsetup-generator understands the following kernel command line parameters:

       luks=, rd.luks=
           Takes a boolean argument. Defaults to yes. If no disables the generator entirely.
           rd.luks= is honored only by initial RAM disk (initrd) while luks= is honored by both
           the main system and the initrd.

       luks.crypttab=, rd.luks.crypttab=
           Takes a boolean argument. Defaults to yes. If no causes the generator to ignore any
           devices configured in /etc/crypttab (luks.uuid= will still work however).
           rd.luks.crypttab= is honored only by initial RAM disk (initrd) while luks.crypttab= is
           honored by both the main system and the initrd.

       luks.uuid=, rd.luks.uuid=
           Takes a LUKS super block UUID as argument. This will activate the specified device as
           part of the boot process as if it was listed in /etc/fstab. This option may be
           specified more than once in order to set up multiple devices.  rd.luks.uuid= is
           honored only by initial RAM disk (initrd) while luks.uuid= is honored by both the main
           system and the initrd.

           If /etc/crypttab contains entries with the same UUID, then the options for this entry
           will be used.

           If /etc/crypttab exists, only those UUID specified on the kernel command line will be
           activated in the initrd or the real root.

       luks.key=, rd.luks.key=
           Takes a password file as argument.

           For those entries specified with rd.luks.uuid= or luks.uuid=, the password file will
           be set to the password file specified by rd.luks.key= or luks.key

           rd.luks.key= is honored only by initial RAM disk (initrd) while luks.key= is honored
           by both the main system and the initrd.
