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.
