systemd Developer Lennart Poettering lennart@poettering.net systemd-cryptsetup-generator 8 systemd-cryptsetup-generator Unit generator for /etc/crypttab /usr/lib/systemd/system-generators/systemd-cryptsetup-generator 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@.service8 units as necessary. systemd-cryptsetup-generator implements the generator specification. 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. systemd1, crypttab5, systemd-cryptsetup@.service8, cryptsetup8, systemd-fstab-generator8
