OK, thanks for the information, Markus. 
So far so good.

I recall another problem that somebody had reported after answering "yes".
The chown command in a postinstall script had no effect. That would mean
that at, at least at that site, the program was lacking the Restore privilege.
To test if this is a prevalent problem, a simple test is to put a 
testchown.sh script in /etc/postinstall . setup will then run it and we can
see if the command worked.
