❄️ AlfheimOS ❄️

This repository is home to the Nix code that builds my systems. Issues, PRs and questions are welcome!

If you are from Lemmy or Reddit and want to check config from the screenshot, please, go to this branch;

Modules

The config is modular, you can either specify settings inside flake.nix or/and exclude/include some modules inside profiles directory with:

imports = [
    ./import1.nix
    ./import2.nix
    ...
];

Profiles

The configuration is separated into several profiles:

• Personal - personal laptop/desktop
• Work - work laptop (included in the Personal profile, as I work from home)

Each profile contains a configuration.nix for system-level configuration and a home.nix for user-level configuration. Setting the profile variable in flake.nix automatically sources the correct configuration.nix and home.nix.

Install

I suppose, you already installed NixOS. To get this config running, start by cloning the repo:

git clone https://github.com/Serpentian/AlfheimOS.git ~/.dotfiles

To get the hardware configuration on a new system, either copy from /etc/nixos/hardware-configuration.nix or run:

cd ~/.dotfiles
sudo nixos-generate-config --show-hardware-config > profiles/desktop/hardware-configuration.nix

Don't use my hardware configuration, your system won't boot!

Now, it's time to configure settings.nix (and probably profiles) to your liking. Once the variables are set, then switch into the system configuration by running:

cd ~/.dotfiles
sudo nixos-rebuild switch --flake .

Home manager can be installed with:

nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
nix-channel --update
nix-shell '<home-manager>' -A install

If home-manager starts to not cooperate, it may be because the unstable branch of nixpkgs is in the Nix channel list. This can be fixed via:

nix-channel --add https://nixos.org/channels/nixpkgs-unstable
nix-channel --update

Home-manager may also not work without re-logging back in after it has been installed. Once home-manager is running, the home-manager configuration can be installed with:

cd ~/.dotfiles
home-manager switch --flake .
