Hurd runs on top of our version of RT-Mach. We fixed binary
incompatibility with CMU Mach 3.0.
But, as Roland said, RT-Mach does not support multiboot. So, we ported
a Hurd boot program (hurd/boot/boot.c) to our RT-Mach. This boot
program can boot Hurd as 2nd OS server from Lites, which is an OS
server compatible with 4.4BSD-Lite and FreeBSD 2.2.8.
