Installing one then the other should have no effect in updateing or going back to 'kernel' should have no problem and just update. Mine updated from RT back to Mainline but to go back to defacto RT I will have to edit it. Make any sense? For others that are saying it want update the boot config then you may have something wrong somewhere because it should plain out update it.
