+
+                <para><filename>systemd-update-done.service</filename>
+                is a service that is invoked as part of the first boot
+                after the vendor operating system resources in
+                <filename>/usr</filename> have been updated. This is
+                useful to implement offline updates of
+                <filename>/usr</filename> which might requires updates
+                to <filename>/etc</filename> or
+                <filename>/var</filename> on the following boot.</para>
+
+                <para><filename>systemd-update-done.service</filename>
+                updates the file modification time (mtime) of the
+                stamp files <filename>/etc/.updated</filename> and
+                <filename>/var/.updated</filename> to the modification
+                time of the <filename>/usr</filename> directory,
+                unless the stamp files are already newer.</para>
+
+                <para>Services that shall run after offline upgrades
+                of <filename>/usr</filename> should order themselves
+                before
+                <filename>systemd-update-done.service</filename>, and
+                use the <varname>ConditionNeedsUpdate=</varname> (see
+                <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>)
+                condition to make sure to run when
+                <filename>/etc</filename> or <filename>/var</filename>
+                are older than <filename>/usr</filename> according to
+                the modification times of the files described
+                above. This requires that updates to
+                <filename>/usr</filename> are always followed by an
+                update of the modification time of
+                <filename>/usr</filename>, for example by invoking
+                <citerefentry><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+                on it.</para>
