That's pretty normal Paul, as most of the entries are created in /dev by udev, 
at bootup time, then when you shutdown, those entries cease to exist. So a 
symlink will not hold over a reboot. I think you'd need to make some change 
in udev itself to do what you want.

Do you have more than one optical drive on the machine? I have 3 optical 
drives on one machine (cdrom, cdrom1, and cdrom2), and if I specify which one 
to open the tray on with eject, I can open any of them.
eject  (which as default opens the tray on cdrom)
eject cdrom   (same as above)
eject cdrom1
eject cdrom2

I'm not sure if that's what you're looking for, but have a look at the man 
page for eject.
