 Pyun, the underlying cause of this problem is that SCSI CDROMs are
 enlisted in kern.disks, which is because cd(4) uses disk(9) since
 rev. 1.28 of scsi_cd.c, i.e. also pre-GEOM. Disk(9) is an API for
 disk-like storage devices, i.e. not necessarily limited to hard-
 disks. Therefore I think sysinstall(8) is actually the right place
 to deal with this, rather than geom(4) or libdisk(3), and your
 change in src/usr.sbin/sysinstall/devices.c rev. 1.159 is a fix
 rather than just a work-around. Maybe the comment could be
 improved somewhat but otherwise I think this PR can be closed.
