Re: NFSd not registering on 14.2.

I've tried a lot of different combinations of rc variables.  On 13.3 and
14.1, nfsd in most (non-v4-only) configurations registers to rpcbind as
expected.  This is true of restarting nfsd and using nfsd -r.

However on 14.2, I can't contrive any configuration that registers to
rpcbind.  Minimally, on one fairly quiet 14.1 server, I simply have

nfs_server_enable="YES"
mountd_enable="YES"
mountd_flags="-h <my ipv6 addr> -S"

on another, I have more:

mountd_enable="YES"
nfs_client_enable="YES"
nfs_server_enable="YES"
nfsv4_server_enable="NO"
#nfs_server_flags="-u -t -n 12" # Flags to nfsd (if enabled).
nfsuserd_enable="YES"
nfsuserd_flags="-domain daveg.ca"
nfscbd_enable="YES"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"

readup for what the 14.2 server has --- but I've tried configurations going
from the former to the latter.  None of them register.
