[apparmor] owner usage for @{HOME} rules

[Simon Deziel]

Hi all,

I am wondering why some of the profile abstractions are not using the
owner prefix with the variable @{HOME} while many others do (and some
mix both)?

Some stats from my Ubuntu 12.04 box:

$ grep -crE '^[[:space:]]*@{HOME}' /etc/apparmor.d/abstractions/ | grep
-v :0$
/etc/apparmor.d/abstractions/kde:7
/etc/apparmor.d/abstractions/X:2
/etc/apparmor.d/abstractions/audio:3
