    'c' presumes a disklabel is present.  The only reason it works (or worked)
    at all was because the kernel faked a disklabel for the CD.

    DragonFly is more of a stickler for using the correct device path. 
    'c' will probably still work for mounting purposes, as will 'a', but
    probably only if the CD already has an ISO filesystem on it.

    Raw accesses for burning operations need to specify the raw device,
    which would be /dev/cd0, /dev/acd0, or whatever.
