Does a CD-ROM drive also have a UUID like a hard drive? How do I determine what the UUID is?

No, they don't.

As this Ubuntu wiki says,

  1. all filesystems should be specified by UUID= or LABEL= for each partition.

  2. all physical devices should be specified by a symlink, like /dev/cdrom for a cd drive and /dev/disk/by-id/... for each physical hard drive.

To find the UUID of devices, run the following command:

sudo blkid
