If you place a card in the slot the shield boot to RC1, so there must be a trigger that senses the card and then forks off to the  hidden copy of the operating system. there is a read only section that is accessible in fail safe mode.

Maybe if a shield fails to boot a sd card could be placed in the slot and see if it boots to RC2 and then that makes it a lot easier to restore, just a thought.
