+ <title>Description</title>
+
+ <para><filename>systemd-suspend.service</filename> is
+ a system service that is pulled in by
+ <filename>suspend.target</filename> and is responsible
+ for the actual system suspend. Similar,
+ <filename>systemd-hibernate.service</filename> is
+ pulled in by <filename>hibernate.target</filename> to
+ executed the actual hibernation.</para>
+
+ <para>Immediately before entering system suspend and
+ hibernation
+ <filename>systemd-suspend.service</filename> will run
+ all executables in
+ <filename>/usr/lib/systemd/system-sleep/</filename>
+ and pass two arguments to them. The first argument
+ will be "<literal>pre</literal>", the second either
+ "<literal>suspend</literal>" or
+ "<literal>hibernate</literal>", depending on the chosen
+ action. Immediately after leaving system suspend and
+ hibernation the same executables are run, but the
+ first argument is now "<literal>post</literal>". All
+ executables in this directory are executed in
+ parallel, and execution of the action is not continued
+ before all executables finished.</para>
+
+ <para>Note that scripts or binaries dropped in
+ <filename>/usr/lib/systemd/system-sleep/</filename>
+ are intended for local use only and should be
+ considered hacks. If applications want to be notified
+ of system suspend and resume there are much nicer
+ interfaces available.</para>
