I had been dabbling with NixOS for a year or more and liked it but without deep knowledge it's fairly hard to approach. I've gotten partially working setups in the past, but a couple weeks ago I decided to go all or nothing.

Now I have a workstation setup that I can reproduce by just grabbing my home directory and /etc/nixos and doing a rebuild.

And it's a somewhat complicated setup. It entirely configures vim (2500 lines of nix config for that, but it's in one file rather than sprayed all over like astrovim), builds gitbutler CLI, has all my secrets encrypted with SOPS, manages my git configs and my ~/bin directory, has sway set up, finally has audio and ability to screenshot (something that had been broken on my 22.04 Ubuntu and I just didn't want to bother with).

NixOS + Claude Code to manage it is really, really good.
