Yes, that makes a lot of sense. But I guess there will be quite a few
packages that will break, so maybe this is a feature for F13?

It would probably need to be mass-edited. Most ldconfig calls have a
typical scheme as a shell replacement, so one could catch a lot
automatically. At the very least it would allow to identify and
bugzilla packages that have ldconfig uses in non-typical ways. I just
wonder if there are implicit uses of ldconfig in other tools used
during install time we might be missing.
