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 * Canonical Ltd * Ubuntu Service and Support * +1 514 691 7221 * Linux for Human Beings.
