    - move log into metadata part of disk, so that marking
    that the log's blocks are in use falls out for free
    - superblock describes the whole disk (sizes and offets)
    - sizes and offsets are computed in one place (mkfs) and
    the rest of the code refers to the superblock for these values,
    instead of recomputing them.
