Filesystems like ext2 put their superblock 1 block into the partition in order to avoid overwriting disk labels and other uglies. UFS does this too, as do several others. One of the few exceptions I've been able to find is XFS. This is a real issue on sparc where the default sun disk labels created use an initial partition where block zero aliases the disk label. It took me a few iterations before I figured out why every btrfs make would zero out my disk label :-/ - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
