I agree the the jailtime.org images would be nice as ready to be used
with pygrub, but that would required putting a working, compatible
kernel within the image. This is possible, but sometimes tricky. You
should contact the jailtime.org admin, he is usually pretty good about
trying to add images and features.

There is at least one alternative that I am familiar with, rpath.com
has quite a few prebuilt images, some of which are designed to work
with pygrub out of the box. We covered how to do this in our book, but
(if you can't or don't want to buy the book) we have also provided a
fair number of resources on our website for the book as well.

For some ideas and other places to get prebuilt images See:
