nixos-config

my public nixos config

my notes

initial setup

• sudo nano /etc/nixos/configuration.nix
• add git, wget, neovim
• sudo nixos-rebuild switch

let's add flakes

• add nix.settings.experimental-features = [ "nix-command" "flakes" ]; to configuration.nix
• sudo nixos-rebuild switch
• create flake.nix:

{
  description = "my nixos flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
  };

  outputs = { self, nixpkgs, ... }@inputs: {
    nixosConfigurations.nixos = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        ./configuration.nix
      ];
    };
  };
}

• sudo nixos-rebuild switch

manage system configuration in a home directory

• git config --global user.name SylviaWhittle

• git config --global user.email sylviwhittle@gmail.com

• ssh-keygen -t ed25519 -C "sylviwhittle@gmail.com"

• add passphrase ofc

• eval "$(ssh-agent -s)"

• ssh-add ~/.ssh/id_ed25519

• cat ~/.ssh/id_ed25519.pub make sure this is the public one

• github > add new ssh key > paste

• sudo mv /etc/nixos /etc/nixos-backup

• mkdir ~/nixos-config

• sudo ln -s ~/nixos-testing /etc/nixos

• cp /etc/nixos-backup/* ~/nixos-config

• ls ~/nixos-config

• ls /etc/nixos

• should both have the files in

• cd nixos-config

• git init

• git branch -m main

• git add ./

• git commit -m "Initial nixos configuration"

• git remote add "origin" git@github.com:SylviaWhittle/nixos-config.git

• git branch --set-upstream-to=origin/main main

• git config pull.rebase false

• git pull

• git push

now i have a git tracked flake config ✨

sudo nix flake update
