>But it is really hard to ignore your own biases. Of course you know that certain commands require sudo and obviously when you wrote -foo you meant --foo and everyone knows that you have to reboot afterwards.

For God's sake, this is not "biases," wtf?? That's straight up just not reading/following the document you're supposed to be testing/reviewing. When I test my documents I actually follow them exactly, step by step, and I always catch these sorts of mistakes. Always. I always copy/paste commands because I know that is what the customer will do, so I have to make sure that works flawlessly.

Dude, if you actually follow your own document, you don't have to pay people to do it for you. Also, you can make sure the person you are paying doesn't ignore the document like you apparently do.

I stopped reading, I'm not interested in whatever else this dude has to say. I'm literally flabbergasted.

Maybe it's because my documents have always gone to real paying customers who have to get through this install, and not some hobby project I'm super proud of or whatever and I don't think I'm super clever? Idk.
