Hi, Nio.

Yes, I was aware that I could do such a restore in two steps, and have 
used that setup at least once.  But I wanted the cheapest, simplest 
thing to give away with a computer to someone with no more than average 
skills.  ("Just boot with this .....")

I have had a fair amount of exchange about this on the Ubuntu users 
forum, much of it exploring the idea of using dd in conjunction with 
utilities that zero-fill free space (as a preliminary step) and then 
compress and split the resulting dd archive.  But that idea stalled at 
the point where there was no apparent way to input the DVD splits to dd 
during a restore.  (Also a challenge with removing the boot disc and 
replacing it with a data disc, but I imagined that could probably be 
solved with a small distro that boots to memory.)

After I last posted there, I also encountered PING, which may possibly 
do what I wanted, at least on a dual boot setup with Win Vista.  But it 
and its backend partimage are apparently no longer under active 
development,  and people report some problems with Win 7, so I already 
regard it with less enthusiasm and have not had a closer look.  (But 
interesting to note that partimage is one of the alternate backends 
employed by Clonezilla, so they must think it is reliable for certain 

I've concluded that, for the moment, I can't get quite what I was 
looking for.  My choices are among half a dozen solutions that are a 
compromise on one goal or another.
