is a service that is invoked as part of the first boot
after the vendor operating system resources in
<code class="filename">/usr</code> have been updated. This is
useful to implement offline updates of
<code class="filename">/usr</code> which might requires updates
to <code class="filename">/etc</code> or
<code class="filename">/var</code> on the following boot.</p><p><code class="filename">systemd-update-done.service</code>
updates the file modification time (mtime) of the
stamp files <code class="filename">/etc/.updated</code> and
<code class="filename">/var/.updated</code> to the modification
time of the <code class="filename">/usr</code> directory,
unless the stamp files are already newer.</p><p>Services that shall run after offline upgrades
of <code class="filename">/usr</code> should order themselves
before
<code class="filename">systemd-update-done.service</code>, and
use the <code class="varname">ConditionNeedsUpdate=</code> (see
<a href="systemd.unit.html"><span class="citerefentry"><span class="refentrytitle">systemd.unit</span>(5)</span></a>)
condition to make sure to run when
<code class="filename">/etc</code> or <code class="filename">/var</code>
are older than <code class="filename">/usr</code> according to
the modification times of the files described
above. This requires that updates to
<code class="filename">/usr</code> are always followed by an
update of the modification time of
<code class="filename">/usr</code>, for example by invoking
<a href="touch.html"><span class="citerefentry"><span class="refentrytitle">touch</span>(1)</span></a>
on it.</p></div><div class="refsect1"><a name="idm214186603664"></a><h2 id="See Also">See Also<a class="headerlink" title="Permalink to this headline" href="#See%20Also">¶</a></h2><p>
