well, _my_ interest for this is to use a cdrom to boot a kernel
where the OS is on a fibre device (lsi) that doesn't support
booting. So the bios boots the /netbsd on cdrom and proceeds to
mount the fibre /dev/sd0a as / (with the same kernel as on the
cdrom for symbols et al).

not essential but would be nice to use the raid-1 from the
disk enclosure for the OS.
