Question though, should we convert an xwhiteout to a regular whiteout when we dump?

This is definitely cool, and will help tons to avoid loads of loopback devices e.g. in the container image case. I agree that the mount code complexity is growing, in...

@allisonkarlitskaya Its needed on e.g. rhel9 at least I belive.

Yeah, EROFS is simpler than read-write OSes, but its not dead simple. The original in-kernel composefs was even simpler, and I believe something like that could eventually get fuzzed to...
