While I think of it - if we change this on boot we should also change
reset_image_select to match the currently loaded image. e.g. if
reset_loads_image has defaulted to off and reset_image_select has
defaulted to factory, but the user image has been loaded - that way we
avoid unexpectedly switching to factory if the card gets reset.
