I think that's somewhat orthogonal.  Your commit affects startup
behavior, mine mainly affects behavior following startup.  The question
becomes then, what should happen if br-int exists at startup and then
something else deletes it?  Maybe the answer is "always create br-int if
it's missing" but I don't know.
