Yes.  That's is correct.  You must configure bpf0, and you must also
have a file in /tftpboot that is the name of your machine's IP
address in hex (eg if you have 10.0.0.1, you'd need 0A000001 (or is
that A000001)).  Then rarpd will work for you.  In addition, if you
want to mount a root NFS file system, you must also run mounted -r so
that you can mount the swap file.  Then you have all the normal
exports permissions problems...
