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
automatically anyway).

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).
