I like 1.2, I feel it's least likely to suffer collateral damage, and

doing."

What about adding a new v1.3 superblock which basically has 4 superblocks, 
an old 1.x superblock residing at <end>-<v1.0 superblock size> (new 
location), and then pointers to this block residing where 1.0, 1.1 and 1.2 
superblocks would normally be? Wouldn't that solve "everybodys" problem by 
making it easier to find the superblock regardless of what might have 
happened (drive size changed because of 3ware, someone installed mbr on 
the drive etc).
