    I've tended to think of this as a feature, actually. In Ubuntu, for
    instance, we might have 2.6.15-8 and 2.6.15-9 which represent different
    ABIs from security updates or other changes. If I have a module that is
    intended to be compatible with both, I might setup /lib/modules/generic
    to be a symlink to /lib/modules/2.6.15-9/ and unpack the modules after
    the symlink is expected to be there.

    (I don't think we use this feature right now, but I had tested it and
    noted it before. It's very convenient, since it's the exact same
    behaviour that dpkg itself has)

    Tks,
    Jeff Bailey
