The feeling I get from the discussion you linked above and the
discussion here is that because user can be an idiot and delete
files at random, we should move back to the 80s and store files
like on the casette tapes, at random offset. User can also delete
kernel image and yet, we store it on the filesystem. Maybe we should
also store the kernel image at another raw offset ... and hey, maybe
we should ditch filesystem altogether, just tar everything up and
store it at yet another offset, since user might delete files at
random, just imaging he'd delete libc ...
