I'm sorry Christoph, but have you considered the remote possibility,
that you and Al are both wrong on this one?  Well, there's one
excercise for you.

If you haven't noticed, I don't take "no" for an answer, until I'm
sufficiently convinced that there's a better way.  In this case I
haven't heard a solution, that is remotely close in cleanliness to
what I've proposed.  And also please note that "not merging apparmor"
is _not_ the answer, however much you would like that to be.  So
please try harder to find an alternative, and then I'll listen.
