<title>Description</title>
<para><filename>systemd-hibernate-resume@.service</filename>
initiates the resume from hibernation. It is instantiated with the
device to resume from as the template argument.</para>
<para><filename>systemd-hibernate-resume</filename> only supports
the in-kernel hibernation implementation, known as
<ulink url="https://www.kernel.org/doc/Documentation/power/swsusp.txt">swsusp</ulink>.
Internally, it works by writing the major:minor of specified
device node to <filename>/sys/power/resume</filename>.</para>
<para>Failing to initiate a resume is not an error condition. It
may mean that there was no resume image (e. g. if the system has
been simply powered off and not hibernated). In such case, the
boot is ordinarily continued.</para>
