NixOS and Home Manager configuration for my machines.

From the root of this repository, apply both the NixOS configuration and the Home Manager configuration:

sudo nixos-rebuild switch --flake ./#x220-nixos --show-trace --verbose

From the root of this repository, apply only the Home Manager configuration:

home-manager switch \
  --extra-experimental-features nix-command \
  --extra-experimental-features flakes \
  --flake .#jack@x220-nixos

ℹ️ As long as the configuration of a host (e.g. nixos/hosts/x220/configuration.nix) includes nix.settings.experimental-features = [ "nix-command" "flakes" ]; the --extra-experimental-features flags can be omitted.

home-manager switch --flake .#jack@x220-nixos

I learned a lot by looking at other people's NixOS and Home Manager configurations. Here is a non exhaustive list of repositories I often look at for inspiration, and why I think they are worth mentioning.

• it configures many hosts and many users.

• it's well organized and well documented.
• it configures 20 hosts, from laptops, to a NAS, to a Pinephone.
• it defines many profiles.

• it configures many hosts.
• it manages several versions of nixpkgs.
• it documents how to deploy the configuration to a new machine.
• it cites other Nix configurations to learn from.

• it's well organized and well documented.
• it contains a few notes that explain how to manage this configuration.
• it configures Neovim using an external Nix flake.
• it includes a build script to deploy the configuration to a new NixOS machine.

• it configures many hosts.
• it uses a nice way of organizing age-encrypted secrets.

• it's well documented.
• it has a modular Home Manager configuration.
• it has an extensive hyprland configuration.
• it includes a cachix configuration.

• it's a great starter configuration for Nix beginners.
• it clearly separates the NixOS (system-wide) configuration from the Home Manager (user) configuration. As far as I know, this pattern is followed by most of the Nix community.

• it's well documented. There is a short README in almost any directory. This keeps the documentation focused on a small subset of the entire configuration. I really like this approach.
• the author wrote this NixOS & Flakes Book.

• it's well documented.
• it defines a few GitHub workflows to update Nix flakes.
• it has a modular Home Manager configuration.
• it cites other Nix configurations to learn from.
