There is another closely related problem which also needs fixing and
which also requires GEOM to distinguish between device and media: GEOM's
behaviour when the media changes while the device is open (e.g. burning
a CD). AFAIK, it is not currently possible to properly fixate a CD-R in
FreeBSD; the CDRIOCFIXATE ioctl always fails because once the media has
changed (from blank to non-blank), all access fails until you close and
reopen the device.
