Not all systems put their CDROM in /dev/cdrom. And you can already select the
machine's real CDROM hardware by doing -cdrom /dev/cdrom (or /dev/sr0, etc).
Examples of device files for CDROMs on other systems:

/dev/sr0
/dev/cd0
/dev/sdc0
/dev/acd0c
/dev/cdrom0
/dev/disk1s0
/dev/scsi/sc0d
/dev/dsk/c1t0d0s0
/dev/rdsk/dks0d1vh

And of course many of the numbers here increment on systems with multiple
drives. There is seriously an insane amount of variation of the names of CDROM
drives. Don't assume that it will only be /dev/cdrom and hardcode it that way.
