You also need to resize partitions to the target sizes after copying the image. > 3.

Thanks to both you and Saurabh for the suggestions. And now I'm invoking the ILUGD torture clause: if you suggest something in public, you are automagically volunteered to do it! So when can we expect a first-cut implementation for testing, Ashish? :) In the meantime I found these, which may be useful starting points. SystemImager in particular seems well-suited: http://svn.oscar.openclustergroup.org/trac/oscar http://wiul.org/ http://kaboot.ainkaboot.co.uk/ http://wiki.systemimager.org/ Any more out there?
