When I rebooted I did a 'ls /dev', noticed the proper symlinks and
though all was well. I inserted a dvd to check things out and low and
behold the symlinks disappeared. A quick 'ls /etc/udev/rules.d' showed
no 70-persistent-cd.rules file.
I grabbed the file from my laptop and edited it to match my desktop
setup.
# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-cd-aliases-generator.rules
# file; however you are also free to add your own entries provided you
# add the ENV{GENERATED}=1 flag to your own rules as well.
# TSSTcorp_CDDVDW_SH-222BB (pci-0000:00:11.0-scsi-2:0:0:0)

Here's the steps to get the above:
Note, this is all done in a terminal. There may be a pointy-clicky way
to do it, but this was easiest for me..
If you don't know the device id for your drive, type
$ sudo lshw -C disk
and look for the '*-cdrom' block. The line 'bus info: scsi@2:0.0.0' is
what you're looking for.
$ ls /dev/disk/by-path
will give you the 'pci-000:00:11.0-' portion. This may be the same for
all, not sure.
I'm also not sure about the last commented line, that may just be human
info, but you can get that from /dev/disk/by-id. Mine was ata-
TSSTcorp_CDDVDW_SH-222BB_R8LM68FC5008YP, and I just trimmed off the
first and last parts to match the part my laptop had in it's file.
This bug may be a problem with either a missing or mismatched
/etc/udev/rules.d/70-persistent-cd.rules file.
