<h1>runit - upgrading from previous versions</h1>
<hr>
<h3>0.12.0 or 0.12.1 to 0.13.0 or 0.13.1</h3>
runit's service logging daemon <a href="svlogd.8.html">svlogd</a> now can
be configured to transmit selected log messages through UDP.
For reliable network logging through TCP with support for authentication,
authorization, and encryption, and also on how to use the new feature to
configure syslog compatible remote UDP system logging, see the
<a href="http://smarden.org/socklog/">socklog</a> package.
<h3>0.11.x to 0.12.0 or 0.12.1</h3>
With this version runit supports running under sysvinit on the Solaris
platform.
Replacing init on Solaris is not yet supported.
The service directory now defaults to /var/service instead of /service.
<h3>0.10.0 to 0.11.0 or 0.11.1 or 0.11.2</h3>
This version introduces the new <a href="chpst.8.html">chpst</a> program,
which changes the process state as specified by command line options, and runs
another program with this process state.
<h3>0.9.x to 0.10.0</h3>
No further action from you is required.
<h3>0.8.0 or 0.8.1 to 0.9.x</h3>
The <a href="svlogd.8.html">svlogd</a> program is new.
<i>svlogd</i> is a service logging daemon designed to be run from
<tt>log/run</tt> files, similar to
<a href="http://cr.yp.to/daemontools/multilog.html">multilog</a>.
The <i>runsvdir</i> program no longer propagates the TERM signal to the
<i>runsv</i> processes if it receives one, but exits immediately, and
<i>runsvdir</i> now supports handling of the HANGUP signal, see the
<a href="runsvdir.8.html">man page</a> for details.
<a href="svwaitdown.8.html">svwaitdown</a> has changed to additionally send
the <tt>down</tt> command to the <i>services</i> it works on, if not yet
done.
<h3>0.7.x to 0.8.0 or 0.8.1</h3>
With this version <i>runit</i>'s handling of its magic files has changed
slightly for better support of read-only root filesystems.
You should adapt stages 1 and 3 and <tt>ctrlaltdel</tt> to set file
permissions on the magic files instead of creating and removing them; please
take a look at the examples in <tt>/package/admin/runit/etc/</tt>.
<p>
The <a href="runit.8.html">runit</a> program now calls the <tt>reboot()</tt>
function if possible, and if stage 3 didn't take care of this.
<h3>0.6.0 to 0.7.0 or 0.7.1 or 0.7.2</h3>
This version introduces runlevel support with the new
<a href="runsvchdir.8.html">runsvchdir</a> program. See the
<a href="runlevels.html">runlevels documentation</a> for more information.
<p>
The <a href="runsvdir.8.html">runsvdir</a> and
<a href="runsv.8.html">runsv</a> programs have changed and should be
restarted. If you want to switch runlevels, <tt>runsvdir</tt> must be
restarted. This is done on the next reboot or by following these steps:
<p>
<ul>
<li>
Login on console 5. Bring all services other than the <tt>getty-5</tt>
service down:
<pre>
# cd /service
# for i in *; do if test "$i" != getty-5; then svc -d $i; fi; done
</pre>
<li>
Check for the services being down:
<pre>
# svstat /service/*
</pre>
<li>
If all services other than the <tt>getty-5</tt> service are down, kill
<tt>runsvdir</tt> by sending it a HUP signal:
<pre>
# kill -HUP <pid_of_runsvdir>
</pre>
Replace <tt><pid_of_runsvdir></tt> with the pid of <tt>runsvdir</tt>.
The <tt>runit</tt> program starts the new <tt>runsvdir</tt> program now,
which starts the new <tt>runsv</tt> processes.
</ul>
<h3>0.5.0 to 0.6.0</h3>
There are two new programs, <a href="runsvdir.8.html">runsvdir</a> and
<a href="runsv.8.html">runsv</a>, which replace the
<tt>svscanboot</tt>/<tt>svscan</tt>/<tt>readproctitle</tt>/<tt>supervise</tt>
combination of daemontools. Please adapt <tt>runit</tt>'s stage 2
(<tt>/etc/runit/2</tt>) to use <tt>runsvdir</tt> instead of
<tt>svscanboot</tt>; see the examples in <tt>/package/admin/runit/etc/</tt>.
The change takes effect on the next reboot or if you stop all services and
kill <tt>svscan</tt> and <tt>readproctitle</tt>. <tt>runit</tt> then
automatically restarts stage 2.
<p>
The <a href="svwaitdown.8.html">svwaitdown</a> program has new options: -k
and -x. They are used in <tt>runit</tt>'s stage 3 (<tt>/etc/runit/3</tt>).
Please adapt your <tt>/etc/runit/3</tt> script after the changes to stage 2
have taken effect (<tt>runsvdir</tt> must run instead of
<tt>svscanboot</tt>); see the examples in
<tt>/package/admin/runit/etc/</tt>.
<h3>0.4.1 to 0.5.0</h3>
There is a new program: <a href="utmpset.8.html">utmpset</a>. This program
is used in the getty run scripts to enable local login accounting. You might
want to adapt your getty run scripts <tt>/service/getty-*/run</tt>, see the
examples in <tt>/package/admin/runit/etc/</tt>.
