Another missing module? It is amazing. I am still running into some silly things like this from my 2.4->2.6 transition. Has someone written some guide on how to upgrade a Debian system from 2.4->2.6? If so he should advertise it! I started out with a working 2.4 system, upgraded to 2.6 and found (roughly in order): - psmouse and mousedev are needed to get a mouse in X - capability is needed to get some of my nfs mounts to survive longer than 15 minutes - and now ide-cd is needed to get udev to find my cdrom drives What am I missing? Upgrading is an incremental process to say the least :-) The need for ide-cd wasn't mentioned on the udev page[1] I found either.
