Unfortunately there is a new misfeature in rpc.mountd that crept in
with IPv6 support.
Option '-p <port>' is no longer working, mountd succesfully registers
MNT1 and then fails with -EADDRINUSE for MNT2 and MNT3 on ip4/tcp,udp and
ip6/tcp,udp transports.

If I start mountd without '-p' it succesfully registers all versions
on random ports.

[root@home ~]# rpc.mountd -d all -F 
rpc.mountd: Kernel does not have pseudo root support.
rpc.mountd: NFS v4 mounts will be disabled unless fsid=0

Reverting b551b1fd0052de9b8c674b30c39d9f2a1e9d79cc cures the problem.
but I guess it's not the right thing to do.
