I do have a small linux server in my home, which I maintain it periodically.
I set up this server in 2021, where I know I need a way to record what I have done on this server. I record every service along with the ports and settings in a txt file. It's happy to work with.
But my current blog server? I set it up 5 years ago, and I tried a lot of things on it, try different settings, different service, and I didn't record anything.
You know, when you're young, you just yolo it.
