I purchased a server for the sole purpose of familiarizing myself with the CLI so I don't get royally screwed when I enter a real development environment. However, I have some questions.
I've managed to SSH into my server, all is fine and dandy, installed LAMP too which went flawlessly. Now I'm wondering, the more changes I do, the more cluttered my server will become. Can I revert changes? I don't want to keep customizing things and installing things and just having a cluttered server overall. Where can I track changes to my system?
