    0.90 has a very bad problem, which is that it is hard to distinguish
    between a RAID partition at the end of volume and a full RAID device.
    This is because 0.90 doesn't actually tell you the start of the device.

    Then, of course, there are a lot of limitations on size, number of
    devices, and so on in 0.90.
