+<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.

+</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>
