[gentoo-user] 4 machines - no /dev/cdrom or /dev/dvd anymore

[Mark Knecht]

I think I touched on this a couple of weeks ago but never had time to
dig in. At that time I thought this problem was only on one machine
but now I see it's on every machine I've looked at this morning. Not a
single machine has /dev/cdrom anymore, nor /dev/dvd or any of the
other incantations that have existed forever.

First, this is udev doing (or not doing) this, correct?

As shown below hwinfo see the cdrom drive, and there are long existing
udev rules that appear to want to create the devices. These rules have
worked in the past but don't now.

Are others running Gentoo stable, and in this case udev-171-r9, seeing
this problem?

Anyone recognize what's wrong with the udev rules below, or does udev
no longer generate these devices at all? I understand that the
70-persistent-net.rules stuff has been 'removed'. Is this true for CDs
also or have I botched something up on all these machines?

Thanks in advance and please ask me to post anything else required.
I've gone through the latest Gentoo install docs and don't see that
I'm doing anything other than what they tell me to do but with udev in
such a state of flux I've obviously missed something.

Thanks,
Mark
