Maybe I'm (still) doing it wrong: On second thought neither solution seems to work because both suggest to only keep relations with "boundary=administrative" and "admin_level=2 (or 3)" tags. But as far as I understand, those relations will have other relations as their members. If these other relations do *not* have the above mentioned tags, they will *not* be in the output file (but they should).
Obviously, the --used-node and --used-way approach is not enough here. I'd rather need something like "--used-reference" with some sort of parameter "master_realtion_id=XY". Any ideas?

I too would suggest using Osmembrane for complex tasks like this. If you want to try an alternative way (example): ./osmconvert bayern.osm.pbf --out-o5m >bayern.o5m ./osmfilter bayern.o5m --keep="all boundary=administrative admin_level=2 =3" >borders.osm Works fine too.
