/etc/udev/rules.d/udev.rules from udev-084-4 sets the wrong group for ide CDROM/DVD devices. It appears that the following rule is not being matched:

# permissions for IDE CD devices
BUS=="ide", KERNEL=="hd[a-z]", SYSFS{removable}=="1", SYSFS{media}="cdrom*", NAME="%k", GROUP="optical"

This rule would appear to be applied:

# permissions for ide storage like pcmcia card readers
BUS=="ide", KERNEL=="hd*", SYSFS{removable}=="1", NAME="%k", GROUP="storage"

This means that /dev/hdd (or whatever the cd device is) is owned by root.storage, and not root.optical, which breaks applications like K3b.

Reverting to the rule from an earlier udev.rules fixes the problem:

# permissions for IDE CD devices
BUS=="ide", KERNEL=="hd[a-z]", SYSFS{removable}=="1", PROGRAM="/bin/cat /proc/ide/%k/media", RESULT=="cdrom*", NAME="%k", GROUP="optical"
This task depends upon

to me this osunds you run a custom kernel without the uevent patch applied

I also ran into this problem. What uevent patch? Why would udev break with a vanilla kernel from kernel.org? I would _not_ force your users to use archlinux's kernel.

the uevent patch from abs in kernel26 dir apply this and all is fine, it's the backport from 2.6.16
