    I kind of overloaded CAP_SYS_RAWIO to restrict access to bits
    of arbitrary memory. Maybe this one should require CAP_PTRACE
    and CAP_DAC_OVERRIDE instead.

    What level of interface does it offer? If it's a simple read/
    write, then it's no more RAWIO than /dev/hda.

    Once upon a time I had a big patch which caught a lot of these
    things (funny devices, device setup ioctl()s, etc) but nobody
    seemed interested in it. Really, I think that set of available
    capabilities needs refactoring.

    Matthew.
