Puntbestanden

Literally means "dotfiles" in Dutch: "punt" = "dot", "bestanden" = "files"

What's in here:

• 6 NixOS configs
• a dendritic home-manager config (TODO: list aspects here)
• An unhinged Emacs config
• A lot less lines of neovim lua config compared to my previous attempt

Dendritic

This repository uses the dendritic pattern for monolithic, interconnected NixOS/HomeManager/Nixvim configs. Hence it also uses flake.parts. This might throw you off if you are new to nix and/or nix flakes. You've been warned!

It is meant to make configurations more modular, flexible, and shareable though, so I encourage you to learn from it if you do so desire. If you understand flake.parts, all you need to know is that (almost) every nix file in this tree is a flake.parts module.

Learn more about it (in order of, well, "deepness" or complexity):

• boomer, a reasonably sluggish Ryzen 5 2600 desktop PC

Autounattend

This repository includes an "autounattend" installer ISO, which:

• Installs a nested, pre-defined NixOS configuration
• Without any user interaction required apart from booting it
• Also automatically partitions through disko
• Does not require internet

To create the iso, run nix build .#autounattend-iso.

To run an install demo in QEMU, run nix run .#install-demo.

If you do not have access to the secrets in this repo you'll need to comment out the networking-wifi-passwords import in order to build it.

Beware: the eval time (and disk usage) is very inefficient, because it seems like nix wants to copy around some source directory through the store a couple of times. it is a cool party trick though.

At home

NEW: you can do this in YOUR repo too, with your own target config!

    # needed so the installer partitions the same way you mount your
    # filesystems later
    autounattend.diskoFile = ./disko.nix;

    flake.nixosConfigurations.autounattend = nixpkgs.lib.nixosSystem {
      modules = [
        ./configuration.nix
        ./disko.nix

For myself: How to bootstrap localsend-rs inside of the flake

• Have one of the private keys corresponding to a pubkey listed in .sops.yaml in ~/.config/sops/age/keys.txt.
• nix run nixpkgs#sops -- decrypt secrets/localsend-rs.secret
• Copy the access token
• nix flake lock --extra-access-tokens "$accesstoken"
• nh os switch

Afterwards, through the nixos module, the secret will get loaded into nix.conf and you can nix flake update for example without any manual setup
