Hi, all, I'd like to add one point. This doc gives guidance on creating minor versions, but never addresses major versions. IMO, past variants of NFS have not handled major version changes appropriately. Each one has been assigned a new port number. This is no longer recommended practice (see RFC7605, Sec 7.5). Is this issue addressed in another document? AFAICT, if (when) NFSv5 is developed, it seems to appear to need another port number. If that's the case (and I sincerely hope it isn't), it MUST be the last one assigned to this service. Joe
