Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

<title>Description</title>
|
|
|
|
<para><command>systemd-inhibit</command> may be used to execute a
|
|
program with a shutdown, sleep, or idle inhibitor lock taken. The
|
|
lock will be acquired before the specified command line is
|
|
executed and released afterwards.</para>
|
|
|
|
<para>Inhibitor locks may be used to block or delay system sleep
|
|
and shutdown requests from the user, as well as automatic idle
|
|
handling of the OS. This is useful to avoid system suspends while
|
|
an optical disc is being recorded, or similar operations that
|
|
should not be interrupted.</para>

<listitem><para>Takes either <literal>block</literal> or

the lock prohibits any of the requested operations without

time limit, and only privileged users may override it. If

<literal>delay</literal> is used, the lock can only delay the

requested operations for a limited time. If the time elapses,

the lock is ignored and the operation executed. The time limit

may be specified in
