Get over it! There are workarounds for your problem, so use > them. Please, calm down:-)), I am not fighting, I am just thinking aloud, I have no intention whatsoever to attack your aor anybody else's work / ideas / decisions, etc. The only my doubt was - yes, you upgrade the __server__, so, you look in Changes, upgrade all necessary stuff, or just upgrade blindly (as does happen sometimes, I believe) a distribution - and the server works, fine. What I find non-obvious, is that on updating the server you have to re-configure __clients__, see? Just think about a network somewhere in a uni / company / whatever. Sysadmins update the server, and then NFS-clients suddenly cannot use NFS any more...
