I imagine the only thing it can be is the implementation of sparse
superblocks in ext2fs. At some stage (and I thin it was 2.2) ext2fs was
upgraded to add sparse superblocks i.e. when mke2fs'ing a big disk, fewer
extra copies of the superblock are saved than heretofore, on the basis
that if the first few spares don't work, then the probability is that the
disk is fscked. This saves space on big disks.
