|
|
|
|
<para><filename>systemd-tpm2-setup.service</filename> and
|
|
<filename>systemd-tpm2-setup-early.service</filename> are services that generate the Storage Root Key
|
|
(SRK) if it hasn't been generated yet, and stores it in the TPM.</para>
|
|
|
|
<para>The services will store the public key of the SRK key pair in a PEM file in
|
|
<filename>/run/systemd/tpm2-srk-public-key.pem</filename> and
|
|
<filename>/var/lib/systemd/tpm2-srk-public-key.pem</filename>. It will also store it in TPM2B_PUBLIC
|
|
format in <filename>/run/systemd/tpm2-srk-public-key.tpm2_public</filename> and
|
|
<filename>/var/lib/systemd/tpm2-srk-public-key.tpm2b_public</filename>.</para>
|
|
|
|
<para><filename>systemd-tpm2-setup-early.service</filename> runs very early at boot (possibly in the
|
|
initrd), and writes the SRK public key to <filename>/run/systemd/tpm2-srk-public-key.*</filename> (as
|
|
<filename>/var/</filename> is generally not accessible this early yet), while
|
|
<filename>systemd-tpm2-setup.service</filename> runs during a later boot phase and saves the public key
|
|
to <filename>/var/lib/systemd/tpm2-srk-public-key.*</filename>.</para>
