<h1> The <tt>s6-pivotchroot</tt> program </h1>

<p>
<tt>s6-pivotchroot</tt> performs a <em>pivot_root</em> system call,
then changes root to the new root filesystem and executes a program.
</p>

<h2> Interface </h2>

<pre>
     s6-pivotchroot <em>newroot</em> <em>putold</em> <em>prog...</em>
</pre>

<ul>
 <li> <tt>s6-pivotchroot</tt> sets the root filesystem to <em>newroot</em>,
which must be a mounted filesystem entry point. The old root filesystem
will be available under <em>putold</em> (relative to the old root). </li>
 <li> <tt>s6-pivotchroot</tt> changes directory to the new root, performs
a <em>chroot</em> system call to the new root, and executes <em>prog</em>
with its arguments. <em>prog</em> is searched under the new root. </li>
</ul>
