    That's really not an option when you only have 16-bits in the disk
    label for some of these values, which is the case for Sun disk
    labels and some others (f.e. BSD).

    Jan, please get past this, it's a real issue and we therefore have to
    skip the initial 1K or so in order to provide something even
    approaching sane.

    No modern filesystem should put it's superblock at position zero.
