[pkg-apparmor] Getting #702030 fixed

[u]

Hi intrigeri and Holger,

I would glad if you could eventually comment my latest suggestion on
that bug. Not necessarily on the bug itself, if you think that we should
rather discuss here first. I could then make a summary once we talked it
through.

It would be equally helpful to get some pointers on what I could look
into in order to write this postinstall script.

Thanks,
u.
