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).
