<title>Description</title>
a system service that is pulled in by
for the actual system suspend. Similar,
executed the actual hibernation.</para>
<para>Immediately before entering system suspend and
hibernation
all executables in
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
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>
<para>Note that
never be executed directly. Instead, trigger system
sleep states with a command such as "<literal>systemctl
suspend</literal>" or suchlike.</para>
