Ok, this gives me a list of packages like "<package> install" for
installed packages, "<package> deinstall" for packages marked 'c' in
aptitude (which I have purged now). Packages marked 'A' in aptitude
simply seem to not be in the list (they should get fetched

It is not quite clear to me from the man-page what would happen to
already installed packages. I suppose that set-selections only
affects those packages that are actually in the list.
I would then possibly need to make a diff between my wanted list and
the actual result of `dpkg --get-selections` after installation.
Thanks (to everybody else who answered, too).
