Code review comment for lp:~ted/gnome-session/upstart-unity

That's fine, though you should probably clearly state that from this point on, it won't be possible to start a Unity session without upstart user sessions.

Also a quick note (unrelated to this diff), please don't remove the gnome-settings-daemon.desktop override file in upstart as even though it won't be needed for Unity anymore, it'll still be used by all the other sessions using gnome-session.
