Put the superblock in the correct possition for UFS2... There is a bug in FFS that if we don't put it here (for UFS2), it will forcefully relocate the superblock, and I believe cause data loss.. I have a fix for that, but w/ how many releases are broken, we won't be able to switch to the better _FLOPPY (block 0) for this for a while..
