What about shadow and gshadow? Those now need the systemd module, too 
(but libnss-systemd doesn't currently guarantee that on upgrades from 
old versions).

We already have a RC bug #1116563 tracking that upgrade issue. I would 
recommend installing apt-listbugs, or keeping track of RC bugs some 
other way, before upgrading packages to their experimental versions.
