mdsetimage does the same thing, but supports more kernel executable
sun3's aren't the only systems which support ram disks in their
kernels. When I wanted to built-in ram disk functionality work in
NetBSD/alpha, I found it easier to rewrite rdsetroot from scratch than
to restructure it to support multiple object formats.
The program to configure an /dev/mdXX device is mdconfig.
