   If you're on Debian, debootstrap is your friend.  Even if you're not
on Debian, you can get debootstrap and easily make Debian domUs.  Just
make a filesystem image, loopback mount it, then run something like (as
root):

debootstrap etch <loopback mount point> http://mirrors.kernel.org/debian

Then you can chroot into the image and fixup the fstab and inittab (to
start a getty in the right place).
