[Bug 926976] Re: udev does not create the proper symlinks to /dev/dvd due to the wrong : ENV{ID_PATH} in70-persistent-cd.rules

[Forest]

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 description:
  I am not sure how long this has been, but trying to watch a movie I noticed I don't have any symlinks to /dev/cd,dvd* pointing to sr0. looking in /etc/udev/rules.d/70-persistent-cd.rules  I noticed that ENV{ID_PATH}=="pci-0000:00:1f.2-scsi-1:0:0:0" was the wrong address and a simple change pci-0000:00:1f.2-scsi-0:0:0:0 creates the symlinks.
  (doing udevadm info --query=all --name=sr0 gives the address, but _we_ all know normal everyday working people are not going to know how to do something like that!)
