This appears to be an intended change in yakkety:
commit f45068b560e1694450624dddb1777354723530c8
Author: John Johansen <[email protected]>
Date: Fri Aug 12 08:08:33 2016 -0700
apparmor: default to allowing unprivileged userns policy
To disable set kernel/unprivileged_userns_apparmor_policy = 0
Signed-off-by: John Johansen <[email protected]>
Signed-off-by: Leann Ogasawara <[email protected]>
Which implies the test is now wrong. Also this change has been
backported to other releases with the apparmor backport.
