They won't work for cd in -current, since it uses slices.  You need
to put a slice behind each track or something like that.  This isn't
easy.  Fudging the label is easy but is limited to 7 tracks.  wcd is
too poorly implemented and maintained to use slices.

cdopen() is a trivial wrapper routine defined in a header in the old
scsi drivers.  The main open routine is named cd_open().  In the CAM
drivers, the open routine is named cdopen() again.
