  25     the in-kernel hibernation implementation, known as
  26     <a class="ulink" href="https://www.kernel.org/doc/Documentation/power/swsusp.txt" target="_top">swsusp</a>.
  27     Internally, it works by writing the major:minor of specified
  28     device node to <code class="filename">/sys/power/resume</code>.</p><p>Failing to initiate a resume is not an error condition. It
  29     may mean that there was no resume image (e. g. if the system has
  30     been simply powered off and not hibernated). In such case, the
  31     boot is ordinarily continued.</p></div><div class="refsect1"><a name="idm140707391420128"></a><h2 id="See Also">See Also<a class="headerlink" title="Permalink to this headline" href="#See%20Also">¶</a></h2><p>
