Hmmm, Ok, maybe I've trimmed that trailing "0" from my primary device. 
Here is how it looks now:

$ dmesg | grep -i -e "cd-rom" -e dvd

-- has been quite a while since last reboot, :-)

Where should I put those rules? I believe that /etc/udev/rules.d/70-
persistent-cd.rules is automatically generated by the 75-cd-aliases-
generator.rules. I hope that I can put those rules in a standalone file 
which can overwrite settings in /etc/udev/rules.d/70-persistent-cd.rules.

BTW, that document is about 5 years old now, and my Debian doesn't have 
commands like udevtrigger, udevcontrol and udevtest for udev rules 
testing and debugging and more. 

What are the equivalents for them?

Thanks
