We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

|
|
|
|
<para><command>shutdown</command> may be used to halt,
|
|
power-off or reboot the machine.</para>
|
|
|
|
<para>The first argument may be a time string (which
|
|
is usually <literal>now</literal>). Optionally, this
|
|
may be followed by a wall message to be sent to all
|
|
logged-in users before going down.</para>
|
|
|
|
<para>The time string may either be in the format
|
|
<literal>hh:mm</literal> for hour/minutes specifying
|
|
the time to execute the shutdown at, specified in 24h
|
|
clock format. Alternatively it may be in the syntax
|
|
<literal>+m</literal> referring to the specified
|
|
number of minutes m from now. <literal>now</literal>
|
|
is an alias for <literal>+0</literal>, i.e. for
|
|
triggering an immediate shutdown. If no time argument
|
|
is specified, <literal>+1</literal> is
|
|
implied.</para>
|
|
|
|
<para>Note that to specify a wall message you must
|
|
specify a time argument, too.</para>
|
|
|
|
<para>If the time argument is used, 5 minutes
|
|
before the system goes down the
|
|
<filename>/etc/nologin</filename> file is created to
|
|
ensure that further logins shall not be
|
|
allowed.</para>
