FUD is a marketing term, and implies I had intent to deceive. Really? I expressed a technical opinion, with a degree of uncertainty, just like everyone else does. People who ask questions here are free to take our advice or not, based on their own experience. They are adults, they read “IMO” where it is implied. It is absolutely your right to say that I’m incorrect, or to clarify something I said. If you have test data that shows "ro,soft,tcp" cannot possibly cause any version of the Linux NFS client to cache corrupt data, show it, without invective. That is an appropriate response to my remark. Face it, you over-reacted. Again.
