Comment # 9 on bug 1170709 from Ludwig Nussel

So far there is no problem, just a random not owned file hanging around that
won't get updated. Might turn into a problem in the future, esp when yast
implements what Josef explained. So make sense to take the discussion here into
consideration.

For the issue at hand, short of yast changing to not copy the file as Thorsten
suggested I'd go for the "solution" that is used so far in the main product, ie
just own control.xml in a package. That way at least we won't have a stale, not
owned file hanging around.
