CDROM URIs; the only setting for CDROM URIs is the mount point, cdrom::Mount
which must be the mount point for the CDROM drive as specified in /etc/fstab.
It is possible to provide alternate mount and unmount commands if your
mount point cannot be listed in the fstab (such as an SMB mount). The syntax
is to put "/cdrom/"::Mount "foo"; within the cdrom block. It is important to
have the trailing slash. Unmount commands can be specified using UMount.
