Re: LiveCD

Hi all,

I can verify that these steps work.

I used the tarball from Debian's GNU/Hurd K8 mini-iso and followed the
rest of the steps to create an iso image.  I wrote the resulting iso
to cd, and it booted up on a real system (not qemu) to a single user
shell, just like Andrew's screenshot shows.
