Public bug reported:
Edgy - udev 093-0ubuntu18
On my system I have a CD/DVD drive (/dev/hdc) and a CDRW/DVDRW
(/dev/hdd).
Udev incorrectly sets /dev/dvd and /dev/cdrom to /dev/hdd, which is
understandable as both devices say they can play CDs and DVDs.
Workaround:
I have made a change to /etc/udev/rules.d/60-symlinks.rules that works
on my system but would probably fail if you just had a CD/DVD RW.
My change was this:
ENV{ID_CDROM_DVD}=="?*", ENV{ID_CDROM_DVD_R}!="?*", SYMLINK+="dvd"
ENV{ID_CDROM}=="?*", ENV{ID_CDROM_CD_RW}!="?*", SYMLINK+="cdrom"
Where before the lines read:
ENV{ID_CDROM_DVD}=="?*", SYMLINK+="dvd"
ENV{ID_CDROM}=="?*", SYMLINK+="cdrom"
** Affects: udev (Ubuntu)
Importance: Undecided
Status: Unconfirmed
