Ok, here's what my script for generating a root filesystem for UMl looks
like. There are lots of things hardcoded and it assumes that the target
system will be the same version as the host. The naming scheme for my
home network is characters from "A Midsummer's Night Dream". Use at your
own risk, etc.
