No, it happened when I fixed fsck to actually propagate the error codes
properly. What is happening, is that MNT_UPDATE fails on the root filesystem,
after the changes have been made and now we correctly reboot, instead of
ignoring the error as before. Now as to why MNT_UPDATE fails, I have not
clue because I have not really tried to debug it.
