Applying updates directly on production ?! (Score 2, Informative)

Applying updates directly on production ?! This should not be done on whatever OS. It's not the "Windows way", it's the "stupid way". That said, even under the hypothesis that the argument is not flawed then doing things the proper way would have taken too much time, leading Linux to a greater TCO anyway. What's missing from the entry is the only meaningful study : that there is no absolute best operative system, and every single case is a different story which should be deeply analyzed by itself.
