Of course that assumes that /dev/cdrom is executable. Which it probably isn't. Maybe you
sha1sum < /dev/cdrom
cat /dev/cdrom | sha1sum
The down side of these methods is that to determine the unique ID of the cdrom requires a
full read which takes a while. It'd be nicer if the unique id was perhaps written into
the cd label at burn time. Depends on whether the requirement is for new cds or for all cds.
