[Bug 926976] Re: udev does not create the proper symlinks to /dev/dvd due to the wrong : ENV{ID_PATH} in70-persistent-cd.rules
..recent udev seems to fail to generate these symlinks for internal devices
because ID_PATH is not set and write_cd_rules needs it for the default
by-path method else f.e.
# udevadm test $(udevadm info -q path -n /dev/sr0)
will echo $DEVPATH not supported by path_id. by-id may work.
The by-id method works, however in the factory
/lib/udev/rules.d/75-cd-aliases-generator.rules this is only used for
usb/firewire optical drives, for whatever (deprecated?) reason.
Just override the default rule by creating this simplified
/etc/udev/rules.d/75-cd-aliases-generator.rules:
# These rules generate rules for the /dev/{cdrom,dvd,...} symlinks and
# write them to /etc/udev/rules.d/70-persistent-cd.rules.
ACTION==add, SUBSYSTEM==block, ENV{GENERATED}!=?*, ENV{ID_CDROM}==?*, \
PROGRAM=write_cd_rules by-id, SYMLINK+=$result
fixed it for me.

Ubuntu really has to be quicker at bugreports(like watching grass grow).
I like left this behind due to no activity.. heck I don't even use that
system anymore. maybe somebody who has the time and problem in front of
them can takeover this.

[Bug 926976] Re: udev does not create the proper symlinks to /dev/dvd due to the wrong : ENV{ID_PATH} in70-persistent-cd.rules
I have that problem too. Gnome-mplayer mplayer (and vlc) will not
play commercial dvd as it looks for them in /dev/dvd but they are
mounted in /dev/sr0. My dvd is simply no longer routed to the sr0.
This happens both on my old and new install of Lubuntu 13.10.
So, does Ubuntu no longer support playing commercial videos? That is a
core function for a PC.
You will not fix it... then how do I fix it at my end?

Clarifying the above. In my case it seems that my /dev/dvd is not
mapped (logical name) to cdrom. I suspect that is why this is
happening. If this is the problem, how do I fix it? As well, is this a
hardware problem?

No, they weren't forgotten. Upstream dropped the /dev/cdrom and
/dev/dvd* symlinks long ago, we just carried them a little longer. This
concept of static symlinks has shown to be unreliable with hardware
changes (as you noticed yourself when changing the SCSI drive), and
modern desktops and CD handling software should not assume any of these
links any more but instead ask sysfs or libudev about available CD
drives and their capabilities.

Thanks for the explanation, Martin. I didn't see this mentioned in the
release notes or package changelogs, so I imagine I'm not the only one
left wondering why the upgrade broke what was working before.
For the record:
I didn't change my SCSI drive or anything else about my hardware. I guess the
target change that I mentioned earlier must have been due to something changing
in the kernel since raring.
At least one popular application in the repos still assumes that /dev/dvd will
exist: vlc.

[Bug 926976] Re: udev does not create the proper symlinks to /dev/dvd due to the wrong : ENV{ID_PATH} in70-persistent-cd.rules
I believe the /dev/dvd* symlinks were correctly created in xubuntu 13.04
(raring), but they disappeared when I upgraded to 13.10 (saucy).
My /etc/udev/rules.d/70-persistent-cd.rules file contains rules that
look like they did the job some time in the past, but they refer to a
scsi target that no longer matches my DVD drive, and I notice that there
is no longer any symlink for my drive under /dev/disk/by-path.
I ended up writing custom rules to create the /dev/dvd* symlinks, but I
doubt that most users will be up to that task.
In raring, the rules file was apparently created by these files from the udev
package:
/lib/udev/rules.d/75-cd-aliases-generator.rules
/lib/udev/write_cd_rules
In saucy, there are no such files. Looks the udev package was moved to
the systemd source package in saucy. I suppose the missing files must
have been forgotten during the move?

[Bug 926976] Re: udev does not create the proper symlinks to /dev/dvd due to the wrong : ENV{ID_PATH} in70-persistent-cd.rules
On my system, the missing symlinks are:
/dev/cdrw
/dev/dvd
/dev/dvdrw
The /dev/cdrom simlink is created, apparently by
/lib/udev/rules.d/60-cdrom_id.rules . Maybe it was intended to replace
75-cd-aliases-generator.rules but someone forgot to add the additional
symlinks for CDRW/DVD/DVDRW drives?
