rpc.bootparamd: unable to register BOOTPARAMPROG version 1, udp

["Boo Geum Jung" <bgjung%etri.re.kr@localhost>]

I'd like to setting up the bootparamsd server for diskless booting.
But I've got the flowing error message in i386 server.

====================
/usr/sbin/rpc.bootparamd -d
rpc.bootparamd: unable to register BOOTPARAMPROG version 1, udp
====================

I compiled and installed NetBSD-current i386 version.
What's the problem?
