The install mediums are a basic freebsd kernel with a MFS-root that
provides a cut-down userland including the binary sysinstall. The
kernel tries a few binaries to run as the initial binary, init.
The last item it will try to launch on startup is sysinstall.

You can run sysinstall over any connection, I've had it running on the
local console (of course), serial console, and ssh session.

I'm surprised on how far braille has gotten onto computer systems.
