    actually I think I disagree with you. One thing I've noticed over the
    years is that ext2 layout has one thing going for it: it is simple and
    robust. Maybe "ext2 layout" is the wrong word, "block bitmap and
    direct/indirect block based" may be better. It seems that once you go
    into tree space (and I would call htree a borderline thing there) you
    get both really complex code and fragile behavior all over (mostly in
    terms of "when something goes wrong")
