Just one thing to note... RHEL6/CentOS6 no longer requires the bind
mounts or fsid=0 on the NFS host... the system now defaults to NFS4
being tried first and does some stuff in the background so that the
bindings and fsid=0 is not required... in principle (barring nfs4
specific options) the same exportfs line can be used for nfs3 or
nfs4.... this is a change from 5.X... I thought it was in the release
notes, technical notes or migration guide but I can't locate the
relevant entry now...
