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.options=, rd.luks.options=
	   Takes a LUKS super block UUID followed by an '=' and a string of options separated by commas as argument. This will override the
	   options for the given UUID.

	   If only a list of options, without an UUID, is specified, they apply to any UUIDs not specified elsewhere, and without an entry in
	   /etc/crypttab.

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

       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.
