The config's the same for 5.8 and 6.3, I think. I do know my manager
worked on it some, and had done some work with NFS 4 configuration.

I can check with my manager, but I believe that we'd be willing to send
that to RHEL; I don't know that he'd want it posted publicly, for security
reasons (but I could be wrong; I'll ask him).

This is 100% reproducible. A user found it on CentOS 6.2; we tried it on
several servers, then went to an RHEL one. All identical responses.

At what point would you decide to "allow" me to be antagonistic?

Let me restate my case: I opened a bugzilla case under my own account.
After weeks, I used the email address for support: yes, we *do* have a
contract with RHEL, and we are a US federal gov't agency. It's been
something like two weeks, and I've not seen a response.

The *only* thing that happened on the bug was they waited about a month,
then there was a followup, if you read it, that they were on 6.3, and so
they put it to dontfix.

*That's* why I'm posting all over. This is the *first* responses I've
gotten. I guess it *does* take public humiliation.
