What do I like?

I have been spending time tinkering with old laptops, trying to come up with a system or configuration that helps me reformat and install new OS easily without messing up the way I work. Right now it is trying to containerize or rather use something like nix so that I can store all that in Git and be able to reproduce my dev environment easily. Or make it portable by storing all that externally in a USB stick or cloud. And have all my secrets in a physical key like a Yubiikey or just have it inside a password manager in that USB stick.

Feels like unnecessary over engineering but I like it :D
