  58                 initiates the resume from hibernation. It is
  59                 instantiated with the device to resume from as the
  60                 template argument.</para>
  61
  62                 <para><filename>systemd-hibernate-resume</filename> only supports
  63                 the in-kernel hibernation implementation, known as
  64                 <ulink url="https://www.kernel.org/doc/Documentation/power/swsusp.txt">swsusp</ulink>.
  65                 Internally, it works by writing the major:minor of specified
  66                 device node to <filename>/sys/power/resume</filename>.</para>
  67
  68                 <para>Failing to initiate a resume is not an error condition.
  69                 It may mean that there was no resume image (e. g. if the
  70                 system has been simply powered off and not hibernated). In
  71                 such case, the boot is ordinarily continued.</para>
