When I put my external DVD drive on my computer the devices look like this:
---snip---
/dev/dvd -> /dev/cd/dvd-4:0:0:0
/dev/cd/dvd- -> /dev/sr0
---snip---
I can access the drive via /dev/sr0, /dev/cd/dvd- and even /dev/scd0 but not via
/dev/dvd, because of the wrong enty in /dev/cd
This what I got from the debug messages:

---snip---
The right entries are removed in favour of the wrong entries and I have no idea
why that is. Since I can't find the creation of this symlink anywhere in the
udev scripts. I use the current udev version and the hal version from testing.
But I think it is related to this rule in 81-arch.rules:
---snip---
ENV{ID_CDROM}=="?*", SYMLINK+="cd/cdrom-%b"
ENV{ID_CDROM_CD_RW}=="?*", SYMLINK+="cd/cdrw-%b"
ENV{ID_CDROM_DVD}=="?*", SYMLINK+="cd/dvd-%b"
ENV{ID_CDROM_DVD_R}=="?*", SYMLINK+="cd/dvd-%b"
---snip---
The variable %b is missing. Where does this rule file gets its variables?
I hope someone can help me.
