Code review comment for lp:~mdeslaur/upstart/apparmor-support

I think that'd make sense, that's how setuid/setgid and other privileged stanzas behave currently so it'd be consistent.

Running init against the session bus and without user mode isn't very common, the biggest use case for this is development.

The use case for running a session init as root isn't yet present in Ubuntu but may be in the relatively near future where we want to have upstart spawned by a PAM plugin even for text consoles (exact details are yet to be specced) so in that case you'd get a Session Init for the root user.
