<title>Description</title>
<para><command>systemd-hibernate-resume-generator</command> is a
generator that initiates the procedure to resume the system from hibernation.
It instantiates the
<citerefentry><refentrytitle>systemd-hibernate-resume@.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
unit according to the value of <option>resume=</option> parameter
specified on the kernel command line, which will instruct the kernel
to resume the system from the hibernation image on that device.</para>
