can i run a fully and exclusively NFSv4 network?

[Robert P. J. Day]

  a while back, i noted on fedora 12 that it seemed impossible to try
to run NFS exclusively in version 4 mode:

https://bugzilla.redhat.com/show_bug.cgi?id=552144

i just noted the same thing on centos/rhel 5.5.  that is, if i edit
/etc/sysconfig/nfs and uncomment the lines:

MOUNTD_NFS_V1="no"
MOUNTD_NFS_V2="no"
MOUNTD_NFS_V3="no

i would have thought that this would mean that i'm trying to use NFSv4
exclusively.  but if i try that, i still get that same error from
mountd on rhel as i did on fedora.

  i've verified that, to get around it, i simply need to advertise at
least one of those earlier versions, doesn't matter which one.  so,
according to red hat's jeff layton, that's still a bug in mountd,
correct?

  and in a larger context, if you had control over an entire network
in terms of NFS both client and servers, is it feasible to run the
entire network using only NFSv4?  thanks.
