Code review comment for lp://qastaging/~tyhicks/lightdm/guest-session-policy-updates

Note that the changes that depend on apparmor/linux unreleased changes should remain in debian/patches since other distributions use lightdm. We have other Ubuntu specific changes in there currently.

In this case I'm not sure how many people rely on the apparmor scripts so it's probably not going to be a problem. I'd like to split these out of lightdm at some point since they are very Ubuntu specific.
