<h1>runit - use with traditional init</h1>
<hr>
It's possible to use <i>runit</i>'s service supervision without replacing
the <i>init</i> scheme of the system.
Simply run the <i>stage 2</i> of <i>runit</i> as a service with your
current <i>init</i>.
<p>
Normally this is done by either adding <tt>/etc/runit/2</tt> as command to
</tt>/etc/rc.local</tt>, or by adding an entry for <tt>/etc/runit/2</tt> to
<tt>/etc/inittab</tt>.
<p>
In either case, you first need to copy the <i>stage 2</i> script to
<tt>/etc/runit/2</tt>:
<pre>
  # mkdir -p /etc/runit
  # cp -p /package/admin/runit/etc/2 /etc/runit/
</pre>
<hr>
If your system uses a sysvinit alike init scheme with a <tt>/etc/inittab</tt>
file, do:
<pre>
  # cat &gt;&gt;/etc/inittab &lt;&lt;EOT
  SV:123456:respawn:/etc/runit/2
  EOT
</pre>
and tell <i>init</i> to reread its configuration, e.g.:
<pre>
  # init q
</pre>
<hr>
If your system uses a BSD alike init scheme with a <tt>/etc/rc.local</tt>
script, do:
<pre>
  # cat &gt;&gt;/etc/rc.local &lt;&lt;EOT
  /etc/runit/2 &amp;
  EOT
</pre>
and reboot your system.
