SYSTEMD-TPM2-GENERATOR(8) systemd-tpm2-generator SYSTEMD-TPM2-GENERATOR(8)
NAME
systemd-tpm2-generator - Generator for inserting TPM2 synchronization
point in the boot process
SYNOPSIS
/usr/lib/systemd/system-generators/systemd-tpm2-generator
DESCRIPTION
systemd-tpm2-generator is a generator that adds a Wants= dependency from
sysinit.target to tpm2.target when it detects that the firmware
discovered a TPM2 device but the OS kernel so far did not. tpm2.target
is supposed to act as synchronization point for all services that
require TPM2 device access. See systemd.special(7) for details.
The systemd.tpm2_wait= kernel command line option may be used to
override behaviour of the generator. It accepts a boolean value: if true
then tpm2.target will be added as synchronization point even if the
firmware has not detected a TPM2 device. If false, the target will not
be inserted even if firmware reported a device but the OS kernel does
not expose a device for it yet. The latter might be useful in
environments where a suitable TPM2 driver for the available hardware is
not available.
systemd-tpm2-generator implements systemd.generator(7).
