This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<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
