The primary reason this code was originally written was to permit field upgrades by having a "ping-pong" boot. If the boot of the newly installed system failed a number of times in a row, then it fell back to using the old "root" device, which contained the previous revision. The point of the exercise is to not turn a working machine into a doorstop with a field upgrade that fails, or happens to be a bad and/or hacked load. What problem are you trying to solve? If it isn't the one that the code was originally intended to solve, then it must be some other problem that we just aren't seeing?
