Albert Einstein quote
Insanity: doing the same thing over and over again and expecting different results
Often-times, Linux drives me mad because I'm doing the same thing over and over again and getting different results from box to box. (See my previous question).
For me, the biggest area of confusion is taking over a machine that someone else has installed (as is the case when signing up with a web hosting company). You just don't know what you're dealing with.
Is there some kind of clever diff tool that I can run on an installation of Linux (Ubuntu) to give me a heads-up on how that machine has veered from the default installation?
i.e. Something that can show me a list of the commands that are going to behave surprisingly thus avoiding a trial and error approach.
