How much of this is to do with %post scripts?

IMHO we should reduce and remove the use of scripts as far as possible
over the whole of Fedora.  RPM upstream too, but that may be harder.

We should replace %post scripts with more intelligence in RPM, so it
can, for example, create (and _delete_) user accounts on demand, or
run ldconfig when required.
