        A gateway should be an IP on the same network, so 192.168.2.X,
        though I don't think that is the issue in this case.

        If those are all on the same filesystem you should have a
        single entry in exports of the base mountpoint with -alldirs

        Is the kernel in /root/ really netbsd.gz - culd you gunzip
        it to test?

        It may also be worth confirming if boot.net is getting its
        answers via bootparams or bootp/dhcp.

        Assuming you're still not having any luck, could you:
        - Attach your bootparams file
        - Run 'tcpdump -s0 -w /tmp/tcpdump.log' during the booting
          process (best to not be doing anything else interesting on the
          net at the same time :)
