+
+    <para><filename>systemd-machine-id-commit.service</filename> is an
+    early boot service responsible for committing transient
+    <filename>/etc/machine-id</filename> files to a writable disk file
+    system. See
+    <citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
+    for more information about machine IDs.</para>
+
+    <para>This service is started after
+    <filename>local-fs.target</filename> in case
+    <filename>/etc/machine-id</filename> is a mount point of its own
+    (usually from a memory file system such as
+    <literal>tmpfs</literal>) and /etc is writable. The service will
+    invoke <command>systemd-machine-id-setup --commit</command>, which
+    writes the current transient machine ID to disk and unmount the
+    <filename>/etc/machine-id</filename> file in a race-free manner to
+    ensure that file is always valid and accessible for other
+    processes. See
+    <citerefentry><refentrytitle>systemd-machine-id-setup</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    for details.</para>
+
+    <para>The main use case of this service are systems where
+    <filename>/etc/machine-id</filename> is read-only and initially
+    not initialized. In this case, the system manager will generate a
+    transient machine ID file on a memory file system, and mount it
+    over <filename>/etc/machine-id</filename>, during the early boot
+    phase. This service is then invoked in a later boot phase, as soon
+    as <filename>/etc</filename> has been remounted writable and the
+    ID may thus be committed to disk to make it permanent.</para>
