I tried and got stuck on this:
# bpsh 0 rpc.mountd --no-nfs-version 3
svc_tcp.c - cannot getsockname or listen: Invalid argument
mountd: cannot create tcp service.
** Any explanation is more than welcome. **
Related (I hope) source code can be seen here:

For the rest, NFS server on scyld node seemes possible. So far I
managed to start these (more or less related) parts:
# bpsh 0 rpcinfo -p
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 806 status
100024 1 tcp 808 status
100021 1 udp 1025 nlockmgr
100021 3 udp 1025 nlockmgr
100011 1 udp 943 rquotad
100011 2 udp 943 rquotad
100003 2 udp 2049 nfs
The rpc.mountd problem might be related to resolver/names oddities,
e.g. netstat says:
# bpsh 0 netstat
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 .0:1592 .-1:1936 ESTABLISHED
tcp 0 0 .0:1591 .-1:1936 ESTABLISHED
tcp 0 0 .0:1590 .-1:1936 ESTABLISHED
tcp 0 0 .0:1589 .-1:1937 CLOSE
tcp 1 0 .0:1432 .-1:1852 CLOSE_WAIT
...
tcp 0 0 .0:615 .-1:2223 ESTABLISHED
Active UNIX domain sockets (w/o servers)
Proto RefCnt Flags Type State I-Node Path
This certainly does not look as usual and mountd might get confused.
Thanks for any comments
