Yes, but init also does a kill(-1,...) to get rid of all processes, before the last steps of system shutdown. So you have to somehow make your "page holding" process survive beyond this point.

You make it a different problem by assuming that you'd have a kernel that is specifically built for running at a "safe" location. If you assume that you're just using your normal kernel, the two problems converge again. There are still a few things that are different, like the checksumming, but they can safely be added at a later time.
