systemd-veritysetup-generator - Unit generator for integrity
protected block devices
Синопсис (Synopsis)
/usr/lib/systemd/system-generators/systemd-veritysetup-generator
Описание (Description)
systemd-veritysetup-generator is a generator that translates
kernel command line options configuring integrity-protected block
devices (verity) into native systemd units early at boot and when
configuration of the system manager is reloaded. This will create
systemd-veritysetup@.service(8) units as necessary.
Currently, only a single verity device may be set up with this
generator, backing the root file system of the OS.
systemd-veritysetup-generator implements systemd.generator(7).
Командная строка ядра (Kernel command line)
systemd-veritysetup-generator understands the following kernel
command line parameters:
systemd.verity=, rd.systemd.verity=
Takes a boolean argument. Defaults to "yes". If "no",
disables the generator entirely. rd.systemd.verity= is
honored only by the initial RAM disk (initrd) while
systemd.verity= is honored by both the host system and the
initrd.
roothash=
Takes a root hash value for the root file system. Expects a
hash value formatted in hexadecimal characters of the
appropriate length (i.e. most likely 256 bit/64 characters,
or longer). If not specified via systemd.verity_root_data=
and systemd.verity_root_hash=, the hash and data devices to
use are automatically derived from the specified hash value.
Specifically, the data partition device is looked for under a
GPT partition UUID derived from the first 128bit of the root
hash, the hash partition device is looked for under a GPT
partition UUID derived from the last 128bit of the root hash.
Hence it is usually sufficient to specify the root hash to
boot from an integrity protected root file system, as device
paths are automatically determined from it — as long as the
partition table is properly set up.
systemd.verity_root_data=, systemd.verity_root_hash=
These two settings take block device paths as arguments and
may be used to explicitly configure the data partition and
hash partition to use for setting up the integrity protection
for the root file system. If not specified, these paths are
automatically derived from the roothash= argument (see
above).
systemd.verity_root_options=
Takes a comma-separated list of dm-verity options. Expects
the following options ignore-corruption,
restart-on-corruption, ignore-zero-blocks,
check-at-most-once, panic-on-corruption and
root-hash-signature. See veritysetup(8) for more details.
