I do not thing we want to lose the priority on a factory reset.  We
have to ensure we always
use the firmware level that the user last activated, no matter what.
The "spirit" of a factory
reset is to clear any changes done by the user to defaults of the
firmware.  Ensuring we boot with the right
level of firmware is still required after a factory reset.
