I wonder if a useful option would be to be able to create an image
relative to a _different_ base image. I.e.
- convert old flat image to new relative image, given new base
- convert old relative + old base to new relative image, given new base
Another thing, which might be easier and more useful, would be
instantiating zeros in the source image into holes in the relative
image. To save space, after lots of changes on the virtual hard disk
and some zeroing. (Microsoft has a tool to do this with Virtual PC).
