			<content:encoded><![CDATA[<p>Simplifying by assuming a single partition, a secure network, and <a href="http://cr.yp.to/ucspi-tcp.html">ucspi-tcp</a> already installed on  <code>ORIG</code>&#8230;</p>
<p>Install fresh hard disk in <code>CLONE</code>, and boot from a  FreeBSD rescue floppy.</p>
<p><span id="more-522"></span>Rather than installing, go to the “configure” submenu and do  “fdisk” and “slice.”  Use <code>W Q</code> instead of just <code>Q</code> to quit each one.  Install a boot manager just as if you were building a  new system.</p>
<p>Go back to the main menu and choose “fixit,” then “live  filesystem on CD-ROM.”</p>
<p>Press alt-f4 to switch to the emergency shell.</p>
<p>Start tcpserver on <code>ORIG</code>:</p>
<blockquote>
<pre>tcpserver -vRHl 0 -c 1 10.23.1.1 1234 sh -c '
echo HTTP/1.1 200 OK
echo Content-type: application/octet-stream
echo
exec dump -0f - /'</pre>
</blockquote>
<p>Go back to <code>CLONE</code>:</p>
<blockquote>
<pre>cd /mnt
fetch -q -o - http://10.23.1.1:1234/foo | restore -rvf -</pre>
</blockquote>
