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 superblock 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.
