 No matter: packages get renamed and split in testing, so using
dist-upgrade all the time is a good idea.  upgrade is very

for example, so that package will be held back forever.

nsswitch.conf configures, e.g. password or group lookups.  (The
database files are still built from /etc/passwd and /etc/group, I
