I have mentioned this before (probably a few times), and i am not sure
if this issue is actually what i think it is but i will once again
mention this issue i observed many times.

Excuse me if i am wrong here.

When you change (user space?) access vectors then user space object
managers get confused and stop working. This is now becoming an issue
since core components are object managers (systemd/dbus)

So basically there is no way for distributions to add/remove access
vectors without breaking the running system.

The only solution is immediately switch to permissive mode and to
reboot the system after such an update. And you might not even be able
to cleanly shutdown due to these confused components
