Nope, just the commandline option that filters out IPv4.

Yes, I got about that far, before coming here. ;)
Here is what rpbind does:
-> bind to local transport
nconf = getnetconfigent("local");
init_transport(nconf);
-> bind to all visible transports configured
while ((nconf = getnetconfig(nc_handle))) {
if (nconf->nc_flag & NC_VISIBLE) {
if (ipv6_only == 1 &&

strcmp(nconf->nc_protofmly,"inet") == 0) {
/* DO NOTHING */
} else
init_transport(nconf);
}
}
endnetconfig(nc_handle);
Thanks,

When you specify hosts, rpcbind automatically adds 127.0.0.1 to the
list of addresses, thus the duplicate.
Here is what rpbind does:
-> bind to local transport
nconf = getnetconfigent("local");
init_transport(nconf);
-> bind to all visible transports configured
while ((nconf = getnetconfig(nc_handle))) {
if (nconf->nc_flag & NC_VISIBLE) {
if (ipv6_only == 1 && strcmp(nconf->nc_protofmly,
"inet") == 0) {
/* DO NOTHING */
} else
init_transport(nconf);
}
}
endnetconfig(nc_handle);
The configuration is in /etc/netconfig:
udp6 tpi_clts v inet6udp - -
tcp6 tpi_cots_ord v inet6tcp - -
udptpi_clts v inet udp - -
tcptpi_cots_ord v inet tcp - -
rawip tpi_raw - inet - - -
local tpi_cots_ord - loopback - - -
where 'v' is the NC_VISIBLE flag.
Of course that's a global setting and RPC clients use is too.
