init - a UNIX process no 1
<h2><a name='sect1'>Synopsis</a></h2>
<b>init</b> [ 0 | 6 ]
<h2><a name='sect2'>Description</a></h2>
<b>runit-init</b>
is the first process the kernel starts. If <b>runit-init</b> is started as process
no 1, it runs and replaces itself with <i><b>runit</b>(8)</i>. <p>
If <b>runit-init</b> is started
while the system is up, it must be either called as <b>init 0</b> or <b>init 6:</b>
<dl>
<dt><b>init
0</b> </dt>
<dd>tells the Unix process no 1 to shutdown and halt the system. To signal
<i><b>runit</b>(8)</i> the system halt request, <b>runit-init</b> removes all permissions of
the file <i>/etc/runit/reboot</i> (chmod 0), and sets the execute by owner permission
of the file <i>/etc/runit/stopit</i> (chmod 100). Then a CONT signal is sent to
<i><b>runit</b>(8)</i>. </dd>
<dt><b>init 6</b> </dt>
<dd>tells the Unix process no 1 to shutdown and reboot the
system. To signal <i><b>runit</b>(8)</i> the system reboot request, <b>runit-init</b> sets the
execute by owner permission of the files <i>/etc/runit/reboot</i> and <i>/etc/runit/stopit</i>
(chmod 100). Then a CONT signal is sent to <i><b>runit</b>(8)</i>. </dd>
</dl>
<h2><a name='sect3'>Exit Codes</a></h2>
<b>runit-init</b>
returns 111 on error, 0 in all other cases.
