    No, but you're not emphasizing the ":-(" at the end of the paragraph
    above. The idea that to use specific Jaz drive commands I need to
    "insmod jaz.o" strikes me as a reversal of one of the boldest triumphs
    and biggest differences between Windows and most Unixen.

    The fact that we have *SCSI* and *IDE* drivers, and not Seagate,
    Iomega, Adaptec etc. drivers is something we should not be
    contemplating abandoning.

    So, sure, protect the whole or some portion of the sg drivers with
    CAP_SYS_RAW, but don't think that its still Unix if you have to
    install a device-specific driver for each device that uses a standard
