Bug Description

In precise, containers are not allowed to load profiles. This will be allowed later, but for now apparmor should not prevent things from starting in a container because of failures to load or transition to profiles.

1. /etc/init.d/apparmor should return 0 if in a container

2. /lib/init/apparmor-profile-load should do nothing and return 0 if in a container.

Since the container is already locked into a (customizable) container profile, this is ok.

(Note that admins can have containers running unconfined and with all
capabilities, but that is a special case.)

THis is needed for bug 978147.

Ok, tested this and compared the output of 'aa-status' before and after a reboot. All the profiles are loaded on reboot with the new upstart. Verified that /lib/init/apparmor-profile-load was updated on upgrade. Comparing build logs between 1.5-0ubuntu3 and 1.5-0ubuntu4 (ie, this patch) shows no surprises. Comparing binaries between the same two versions show no surprises either.

I did not test this in containers, but Serge did before giving me the patch and the logic in the script is obvious.

Uploaded to unapproved.

This bug was fixed in the package upstart - 1.5-0ubuntu4

---------------
upstart (1.5-0ubuntu4) precise; urgency=low

  * debian/apparmor-profile-load: don't run in a container. This can
    hopefully be removed after stacked profiles are supported and
    used by lxc. (LP: #978297)
