Hi Russ

Thanks for your review.

This latest round of comments - including the Gen-ART review from Brian Carpenter shows that there is still an impedance mis-match between the title/abstract and the intended status of Standards Track versus an Informational draft or best practices.

I feel that the use of "Guidelines" in the title, and "guidance" in the abstract point to an Informational draft rather than a Standards track.

This draft is a Proposed Standard (not an Informational or BCP) because the MUST and REQUIRED noted in section 6 of the doc are absolute requirements for an NFSv4 multi-domain file name space to work. These can not be BCP as an NFSv4 multi-domain file name space will _not_ work without these requirements.

I have completed a draft-ietf-nfsv4-multi-domain-fs-reqs-10 with the following changes:

1) The title to be changed from

"Multiple NFSv4 Domain Namespace Deployment Guidelines"

to

"Multiple NFSv4 Domain Namespace Deployment Requirements"


2) The first sentence in the abstract (and in the introduction) to be changed from

   This document provides guidance on the deployment of the NFSv4
   protocols for the construction of an NFSv4 file name space in
   environments with multiple NFSv4 Domains.

to
   This document presents requirements on the deployment of the NFSv4
   protocols for the construction of an NFSv4 file name space in
   environments with multiple NFSv4 Domains. 

Another common area of comment concerned the “Stand-alone Examples" examples section 5 and "Stand-alone Examples and Multiple NFSv4 Domain Namespaces” section 8. These section describe "alternatives and differing scenarios” to highlight the need for the requirements described in section 6.

I addressed the example sections comments by adding clarifying text to each of these sections as well as moving the second section from 8 to section 7.


I have also addressed the remaining comments from Brian, Russ, Alexey Melnikov, and Kathleen Moriarty.

I’ll upload the new draft soon.
