Or does > this only affect cases where you are testing squeeze? Could it be I have 30 beta-testers that are affected by this issue on the workstations they have started using for their everyday work. Although it's still a beta phase, at this point, these workstations are to be considered "in production" given the users have basically made the switch now. Full deployment involves over a thousand workstations. > worked around by using DKMS or similar with prebuilt binaries and > requiring exact kernel version dependencies? DKMS is useless if the ABI number doesn't change, in its current form. If DKMS was changed to rebuild all modules when the kernel package is upgraded, we'd still have issues with on-disk modules not matching the running kernel ABI until the machine is rebooted. This can sometimes take two or three weeks if a long-running computation is running on the machine. We switched to DKMS to reduce the maintenance cost associated with prebuilt binaries. We'd rather not come back to that if we can help it. It also adds a delay to kernel updates that we'd rather avoid. As to using strict dependencies... it makes all of the above even worse. And I'll ask again: what's the point of the kernel ABI number if we have to use strict dependencies? Seriously? We need a kernel ABI numbering we can rely on.
