Things should Just Work(tm).

nscd in FC has been patched to prune the password, group and hosts
caches when it receives a SIGHUP, and shadow-utils has been patched to
HUP nscd on relevant operations.
http://cvs.fedora.redhat.com/viewcvs/devel/glibc/glibc-fedora.patch?rev=.&view=auto
http://cvs.fedora.redhat.com/viewcvs/devel/shadow-utils/shadow-4.0.3-nscd.patch?rev=.&view=auto

There was a bug at FC2'ish time where the nscd pid file had moved so
that the HUP never happened.  But that was fixed last year...
