Cheers Todd. I can understand that in a way, but NFSv4 has been around for a long, long time - it's not new, and probably pre-dates DSS v7 anyway. It probably wouldn't have made sense to implement it in DSS v6, but I'd have thought v7 would have had this enabled since the beginning.
Also, one other question then. When you create an NFS 'share' in v7, what's the underlying filesystem used (EXT4/XFS etc). This isn't a block protocol, so it must have an underlying filesystem.
