+ <para><command>systemd-inhibit</command> may be used
+ to execute a program with a shutdown, suspend or idle
+ inhibitor lock taken. The lock will be acquired before

+ afterwards.</para>
+
+ <para>Inhibitor locks may be used to block or delay
+ suspend and shutdown requests from the user, as well
+ as automatic idle handling of the OS. This may be used
+ to avoid system suspends while an optical disc is
+ being recorded, or similar operations that should not
+ be interrupted.</para>
