What worries me is people using amd against a v2 server, also those tunables are good at tickling bugs in other NFS implementations (as well as ours, at least a year or two ago). So if amd is smart enough to downgrade then yes, otherwise perhaps just a comment to indicate that the person may want to use better mount options... ? -- -Alfred Perlstein [alfred@freebsd.org] 'Instead of asking why a piece of software is using "1970s technology," start asking why software is ignoring 30 years of accumulated wisdom.'
