- <para><command>systemd-machine-id-commit</command> may
- be used to write on disk any transient machine ID
- mounted as a temporary file system in
- <filename>/etc/machine-id</filename> at boot time. See
- <citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
- for more information about this file.</para>

- <para>This tool will execute no operation if
- <filename>/etc/machine-id</filename> doesn't contain any
- valid machine ID, isn't mounted as an independent temporary
- file system, of <filename>/etc</filename> is read-only. If
- those conditions are met, it will then write current machine ID
- to disk and unmount the transient
- <filename>/etc/machine-id</filename> file in a race-free
- manner to ensure that this file is always valid for other
- processes.</para>
-
- <para>Note that the traditional way to initialize the machine
- ID in <filename>/etc/machine-id</filename> is to use
- <command>systemd-machine-id-setup</command> by system
- installer tools. You can also use
- <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
