Right, this makes sense. We probably need to remove the
/var/lib/PackageKit/prepared-update file if we do RefreshCache.

Well, the idea is we let the desktop choose what packages to
auto-install at boot time, and let the user override this in the
session. So for GNOME, we're going to let users live-update in the
session apps that are not open and then force everything else to be
done at startup, unless they drop to the command line.
