Comment 4 for bug 1663157

I should mention that the above pstree outputs require some changes to the pstree code to get the AppArmor label included in the output when the -Z option is specified. I've pushed a work-in-progress quality git branch of psmisc to https://code.launchpad.net/~tyhicks/psmisc/+git/psmisc/+ref/apparmor that includes the necessary changes.
