Yeah, that was what I suggested a few times when other people have done
config writing side, but without successfully getting past their skulls
(it is not Linus's nor my code).  It's about time somebody started to
clean up that mess.

The timing is a bit unfortunate, though.  I would have preferred to have
a week or so to cook this in 'next' before merging it part of -rc0.
