Ahhh, good point.  Not personally being a user of AppArmour, it didn't 
occur to me to consider that. ;)

Do you know the exact steps you took to allow the hook scripts to work 
through AppArmor?  (hoping for exact commands here)

If you do, then we'll add them to the hooks documentation. :)

(SELinux may also need a similar thing, which should be looked into as well)
