Yes, sounds reasonable.  But the big question is what package should declare the
hook.  For instance, for the GTK icon cache problem, should the hook be declared
by gtk+, or by every GTK-based package that has a share/icons directory?  In the
former case, this means that gtk+ has to be in the user environment (or be
propagated by some other package).  Also, we should make sure that a hook (like
gtk-update-icon-cache) is executed only once.
