<h1> The <tt>s6-accessrules-fs-from-cdb</tt> program </h1>
<p>
<tt>s6-accessrules-fs-from-cdb</tt> decompiles a CDB database
containing a ruleset suitable for
<a href="s6-ipcserver-access.html">s6-ipcserver-access</a> or
<a href="//skarnet.org/software/s6-networking/s6-tcpserver-access.html">s6-tcpserver-access</a> and
that has been compiled with
<a href="s6-accessrules-cdb-from-fs.html">s6-accessrules-cdb-from-fs</a>.
</p>
<h2> Interface </h2>
<pre>
s6-accessrules-fs-from-cdb <em>dir</em> <em>cdbfile</em>
</pre>
<ul>
<li> s6-accessrules-fs-from-cdb decompiles the
<a href="https://en.wikipedia.org/wiki/Cdb_(software)">CDB file</a>
<em>cdbfile</em> into the directory <em>dir</em>, then exits 0. </li>
</ul>
<h2> Notes </h2>
<ul>
<li> <em>dir</em> must not exist prior to the decompilation. </li>
<li> <em>dir</em> must be considered a work in progress as long as
s6-accessrules-fs-from-cdb is running. It is only safe to use <em>dir</em>
as a ruleset once the program has exited. </li>
<li> If s6-accessrules-fs-from-cdb fails at some point, the partial
arborescence at <em>dir</em> is removed. However, this doesn't happen if
s6-accessrules-fs-from-cdb is interrupted by a signal. </li>
<li> After the program successfully completes, if <em>cdbfile</em>
was a suitable candidate for the <tt>-x</tt> option of
<a href="s6-ipcserver-access.html">s6-ipcserver-access</a> or
<a href="s6-tcpserver-access.html">s6-tcpserver-access</a>, then
<em>dir</em> will be a suitable candidate for the <tt>-i</tt> option
of the same program, implementing the same ruleset. </li>
</ul>
