My whole point has been that it could be done, while you've been saying it 
couldn't.  Having apparently accepted that was wrong you raise spurious 
issues about implementation.  What does where they want their user accounts 
have to do with anything?  Pick a reasonable default and use it.  Ask them 
if they already have a user source, and use that.  If mom & pop are setting 
up an initial system, they'll happily use whatever you give them.

No, they aren't.  I just don't see the difficulty in having an automated 
system make the deltas.  You provide identical disk images of the fixed 
data, and each system gets its own image of the unique data.  Simple rocket
