	I've a few of patches to do something similar, except I've been using
livecd-creator to build xen system images for the likes of image based
deployment (e.g. stateless) or this virtual appliances notion.

	See the attached patches - the first makes LiveCDTarget be a sub-class
of InstallationTarget, the second adds --target and the last adds
RawTarget which I've been playing with.
