CC'ing the bug in question is the best way in all cases.  This lets us
follow the progress of the issue.

No it does not.  That is by design, so I'm told.  Apparently there is
no standard way to include the root image with the TFTP kernel image.
Thus the root filesystem must be loaded and mounted by other means
(root=/dev/nfs kernel boot argument, apparently).

What is mknbi-linux?  Will that work with most/all i386 hardware that
is even capable of netbooting?

Well, it's purely an NFS and kernel issue at this point.  Perhaps you
don't have lockd running on the server?  Have you consulted the docs,
Debian and otherwise?  NetBSD has some pretty good instructions on
this sort of stuff...

Why not from the network?

Well, the fact is, you can't get it working, so I doubt you can help
us much.
