+ <title>Description</title>
+
+ <para><filename>systemd-halt.service</filename> is a
+ system service that is pulled in by
+ <filename>halt.target</filename> and is responsible
+ for the actual system halt. Similar,
+ <filename>systemd-poweroff.service</filename> is
+ pulled in by <filename>poweroff.target</filename>,
+ <filename>systemd-reboot.service</filename> by
+ <filename>reboot.target</filename> and
+ <filename>systemd-kexec.service</filename> by
+ <filename>kexec.target</filename> to execute the
+ respective actions.</para>
+
+ <para>When these services are run they ensure that PID
+ 1 is replaced by the
+ <filename>/usr/lib/systemd/system-shutdown</filename>
+ tool which is then responsible for the actual
+ shutdown. Before shutting down this binary will try to
+ unmount all remaining file systems, disable all
+ remaining swap devices, detach all remaining storage
+ devices and kill all remaining processes.</para>
+
+ <para>Immediately before executing the actual system
+ halt/poweroff/reboot/kexec
+ <filename>system-shutdown</filename> will run all
+ executables in
+ <filename>/usr/lib/systemd/system-shutdown/</filename>
+ and pass one arguments to them: either
+ "<literal>halt</literal>",
+ "<literal>poweroff</literal>",
+ "<literal>reboot</literal>" or
+ "<literal>kexec</literal>", depending on the chosen
+ action. 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
+ <filename>systemd-halt.service</filename> (and the
+ related units) should never be executed
+ directly. Instead, trigger system shutdown with a
+ command such as "<literal>systemctl halt</literal>" or
+ suchlike.</para>
