Get anyone who acts like it’s easy to work on someone’s setup that isn’t their own, and they’ll quickly remember how complicated it all is.
I would agree with this and the sentiments above. If I am on my system, I know how I have it set up. I can reference pages of notes if I do forget how I did something. I am more familiar with my server and services. When it comes to someone else's set up, I can tell you how I did it, and that it works for me. You've got to kind of adapt it to your scenario. I can understand how that would be frustrating for someone starting out, as with Linux, there seems to be a thousand ways to do one thing.
