I am using -current and I have noticed that ever since udev got updated to 130, my /dev/dvd and /dev/cdrom symlinks disappear after inserting a disk.

I dont know if it is my setup or something, and although not many applications actually use these interfaces anymore, mplayer does use it (this should really be a mplayer problem).

After a reboot, all the symlinks are there. However, upon inserting a disk (it will automount through hal), the symlinks all disappear. Udev emits a "changed" event when this occurs.

This happens also to normal cdrom drives. I have two drives: dvdrw and a cdrw (kept after upgrading), both on pata.

Would anyone care to offer any insights into how I can resolve this issue?

have you merged the new rc.udev.new file?

Thanks for you help. In the end I answered my own question. It turns, udev write new rule files for dev and cdrom devices in /etc/udev/rules.d/70-persistent-cd.rules. But because I use a live environment, these files dont exist the next reboot. Under these circumstances, udev wont see these new rules and so any udev event relating to dvd or cdrom drive gets run again and the symlinks dont get recreated.

Thus the solution is to modify line 59 of rc.udev to add " /sbin/udevadm control --reload-rules". It looks like this line should be there anyway because the lines before this add some new tmp-rules to the rules directory. These new rules will not be seen by udev until reload-rules is called on them either.

I could be wrong, but it certainly does solve my problem.
