Shouldn't this be done on RPM level?  Isn't this pretty much an extension of
RPM triggers?  Or it's so hard to do that that we now want to move stuff to yum?

Similar issues that can be automatically handled also:

  - Run gtk-update-icon-cache if icons have been added/removed.

  - Run fc-cache if fonts have been added/removed.

  - Run ldconfig when share objects are installed (this one is done already,
right?)


It's really the same problem.  Many of the RPM snippets we keep copying from
package to package can be automated.  I don't see how this one is different.
