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 doesn't 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).
