Yeah. I had been wanting what Nix does for years, but didn't know what Nix was until 2020? I always had this desire to create a shell script that would allow me to install a clean version of my system, but always got stuck at the part where you try to reverse your current OS state (config and packages) into a shell script. It's just too easy to do "apt-get install..." and then forget about your original intent of having a thing that produces your OS state. NixOS (and its relatives) is way more annoying about getting you to declare your config to get the OS state, which is perfect for a person like me. Being able to rollback packages (no, not individual files or groups of files, but discrete packages) is nice too. > it's so easy to modify/remove/overwrite something For some reason, out of the corner of my eye, I thought you were describing this as a feature of Nix because I missed the "mess up your install" part. It's easy to modify/remove/overwrite a package in Nix in a non-destructive way though. Of the few packages that have been broken for me, I feel empowered to pull them down and modify them to add needed functionality. And as I've gotten more confident, doing overlays or whatever they're called instead.
