Wrong fix. Right one is to have a mini-fs (quite possibly only with the
root directory) and set it from the very beginning. Then all this
special-case crap will go away. I'll do that - BTW, it will simplify the
mount_root() big way. Come to think of that, we might put a file there and
do union-mount of real root over the original one. File being something
like /shutdown that would close all descriptors, umount / (really umount,
none of this remount-ro stuff) and call reboot(9). That's a trivial static
binary and we could let init(8) just exec in the end of everything.
