I tried to used AppArmor under the Linux cubietruck 4.4.1-sunxi #10 SMP Wed Feb 17 17:57:20 CET 2016 armv7l GNU/Linux.
But I get a kernel panic after i rebooted the system.
Some questions:
1. Did you integrate AppArmor into the kernel?
2. Did you use an alternative mandatory access control?
3. Need I an additional kernel argument in the /boot/boot.cmd other than these "apparmor=1 security=apparmor"?
4. Is there a major diffenrece between your kernel and that from danad.de?
Unluck
