Hmm. 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.
Thanks for pointing me in the right direction.
