Thanks Brad,

Your method both worked and was dead bang easy. Yesterday I performed
this procedure about 10 times in 2 hours. Note that System Rescue CD
requires -vga std in order to have anything resembling a decent image.
And of course I used --enable-kvm so I wouldn't get gray hair waiting
for it to boot.

A big thank-you goes out to Peter Maloney for suggesting chroot.
Although chroot technically isn't necessary, using it prevents a lot of
stupid mistakes, so I use it every time and indeed have put it into my
document.

Thanks!
