This is a pity, but, if this is really the case, you can at least document
the situation (hence the reopen). As said initially,
Please send a patch.
To add into the README.Debian (for example, or another specific file):
**
Since jessie, udev does not provide persistent name for CD/DVD readers/
writers (see #655924 for more details). This is not a problem with one
CD/DVD reader/writer (as it will automaticcaly be linked to /dev/cdrom,
/dev/dvd, ...) but it is with more than one hardware. Moreover, in the
latter case, the symlinks (/dev/cdrom, /dev/dvd, ...) can change
each time a CD/DVD is inserted into one reader/writer (as reported in
#774080), even while they are used!
To come back to persistent names, old wheezy users can change their
/etc/udev/rules.d/70-persistent-cd.rules to use ID_SERIAL instead
of ID_PATH. And new jessie installation can manually wrote such a
file. As an example, to be adapted to your hardware, here is
such a file:
==
# DVD-ROM_GD-7500 (pci-:03:05.0-scsi-0:0:0:0)
SUBSYSTEM==block, ENV{ID_CDROM}==?*,
ENV{ID_SERIAL}==HITACHI_DVD-ROM_GD-7500, SYMLINK+=cdrom, ENV{GENERATED}=1
SUBSYSTEM==block, ENV{ID_CDROM}==?*,
ENV{ID_SERIAL}==HITACHI_DVD-ROM_GD-7500, SYMLINK+=dvd, ENV{GENERATED}=1
# DRW-1814BL (pci-:03:05.0-scsi-0:0:1:0)
SUBSYSTEM==block, ENV{ID_CDROM}==?*, ENV{ID_SERIAL}==ASUS_DRW-1814BL,
SYMLINK+=cdrom1, ENV{GENERATED}=1
SUBSYSTEM==block, ENV{ID_CDROM}==?*, ENV{ID_SERIAL}==ASUS_DRW-1814BL,
SYMLINK+=cdrw1, ENV{GENERATED}=1
SUBSYSTEM==block, ENV{ID_CDROM}==?*, ENV{ID_SERIAL}==ASUS_DRW-1814BL,
SYMLINK+=dvd1, ENV{GENERATED}=1
SUBSYSTEM==block, ENV{ID_CDROM}==?*, ENV{ID_SERIAL}==ASUS_DRW-1814BL,
SYMLINK+=dvdrw1, ENV{GENERATED}=1
==
The identifier for ID_SERIAL (or other way to identify the hardware)
can be found by running:
# udevadm info --query=all --name=/dev/sr0
# udevadm info --query=all --name=/dev/sr1
...
And, once these new udev rules are in place, they can immediately be
taken into account (without rebooting) by running:
# udevadm trigger
**
A test for several /dev/sr* file at config time that would display
a debconf notice pointing on this documentation would probably also
be a very good thing.

Vincent
