This is cool as hell. I don't fully understand it, but I like it.<br>
And it looks like it would be handy for other things besides chroot<br>
installations. Would you be able to give an online presentation of this<br>
at the next GoLUG online meeting, via Jitsi, at 7pm the first Wednesday<br>
of June?<br>
<br>
Thanks,<br>
