It's a sentimental thing -- it was the part of the first mail system at
a provincial ISP I admin'ed back in '98. It's still vastly over-powered
for the usage I have planned for it, and I have the other one for

See paragraph 2 under _http://www.netbsd.org/Ports/xen/howto.html_.

That binary doesn't exist on any of my FreeBSD machines. I assume you
meant bsdlabel -B? Digging through the man pages, it looks like
installboot is for NetBSD (which is what I'll need).

Getting to a domain0 system is the next step -- the NetBSD Xen HOWTO is
missing a lot of details around the grub section.
