I'm not sure gnumach + booter + ext2fs.static + ld-2.1.3.so +
(ideally) libc-2.1.3.so would fit. We'll see, anyways.

Mountpoint was not the right term. I was thinking more around the
lines of "kernel (nfs,zalem:/root/melchizedek)/boot/vmlinuz [...])"
with zalem being the remote file server and melchizedek the computer
to boot. I'd like completion on both the path and the export. It's a
bit tricky because it requires udp fragmentation support.

I agree, that was my point. What I think we need is a way to
configure things so that the cost is what isn't needed is zero, and
which makes it easy to remove what has bitrotten.
OG.
