<h1>The user-run program</h1>
<p>
The user-run program allows
to hand over the execution of commands to the
<a href="//0x53.net/software/goetia/supervisiontree.html#user">user supervision tree</a>.
</p>
<h2>Interface</h2>
<pre> user-run <em>prog...</em></pre>
<ul>
<li>
user-rc reads the <code>USER</code> environment variable,
if it is empty it exits 100.
</li>
<li>
It reads the <code>USERTREE</code> environment variable,
if it is empty it exits 100.
</li>
<li>
Internally, user-run invokes
<a href="https://skarnet.org/software/s6/s6-sudo.html">s6-sudo</a>
to connect to an
<a href="https://skarnet.org/software/s6/s6-sudod.html">s6-sudod</a>
instance provided by the user
<a href="//0x53.net/software/goetia/service/user/goetia-runner.html">goetia-runner</a>.
</li>
<li>
<code><em>prog...</em></code> is then transferred
to and executed by goetia-runner.
</li>
<li>
See
<a href="https://skarnet.org/software/s6/s6-sudo.html">s6-sudo</a>
and
<a href="https://skarnet.org/software/s6/s6-sudod.html">s6-sudod</a>
for configuration options and detailed information.
</li>
</ul>
<h2>Exit codes</h2>
<ul>
<li>
100 if a critical environment variable is missing.
</li>
<li>
user-run behaves exactly as
<a href="https://skarnet.org/software/s6/s6-sudo.html">s6-sudo</a>.
</li>
</ul>
<h2>Options</h2>
<ul>
<li>
user-run takes the exact same options as
<a href="https://skarnet.org/software/s6/s6-sudoc.html">s6-sudoc</a>.
</li>
</ul>
