Hmm ... that's a strange idea. AppArmor cannot assume anything about argv[0], 
and it would be a really bad idea to change the well-established semantics of 
argv[0].

There is no actual need for looking at argv[0], though: AppArmor decides based 
on the actual pathname of the executable...

Thanks,
Andreas
