NixOS Configuration

Welcome to my NixOS configuration repository! This is a multi-host flake-based setup supporting both NixOS and Darwin systems. These configurations represent my reproducible, declarative system setups for various machines and use cases.

Repository Structure

• nixos/ - System-level configurations

  • hosts/ - Machine-specific configurations
  • features/ - Modular system features (networking, desktop environments, etc.)
  • common.nix - Extended baseline with fonts and utilities
  • minimal.nix - Minimal baseline for headless systems

• home-manager/ - User-level configurations

  • cli/ - Terminal and command-line tools
  • gui/ - Graphical applications and settings
  • hyprland/ - Hyprland window manager configuration
  • terminal/ - Terminal emulator settings
  • plasma/ - KDE Plasma desktop environment

• modules/ - Reusable NixOS and home-manager modules

• pkgs/ - Custom packages and fonts

• overlays/ - Package modifications

• secrets/ - SOPS-encrypted secrets

Bootstrapping a Linux environment (Home-manager)

sudo apt update && sudo apt install -y curl git gh vim

installing nix

sh <(curl -L https://nixos.org/nix/install) --daemon

installing home manager

nix-channel --add https://github.com/nix-community/home-manager/archive/release-25.11.tar.gz home-manager && nix-channel --update && nix-shell '<home-manager>' -A install

git clone https://github.com/reinthal/nixos-config
cd nixos-config

allow flakes and trust root and current user add devenv public key

sudo tee -a /etc/shells <<EOF
$(which zsh)
EOF

sudo tee -a /etc/nix/nix.conf <<EOF

restart the nix daemon

sudo systemctl restart nix-daemon

sudo tee -a /etc/shells <<EOF
/home/$(whoami)/.nix-profile/bin/zsh

install home-manager cli environment

home-manager switch --flake .#kog@cli --impure -b bkp && &&sudo chsh -s $(which zsh) && echo  'WELCOME TO NIXLAND'  && zsh

Building the System

First Time Setup

For NixOS systems:

sudo nixos-rebuild switch --flake '.#<hostname>' --impure

For Darwin (macOS) systems:

nix run --experimental-features "nix-command flakes" nix-darwin -- switch --flake .#<hostname>

After Initial Setup

Once experimental features for flakes are enabled, use these convenient aliases:

Apply new configurations:

nixswitch

Update system packages and configurations:

nixup

Build specific hosts:

sudo nixos-rebuild switch --flake '.#workstation' --impure
sudo nixos-rebuild switch --flake '.#seed' --impure
sudo nixos-rebuild switch --flake '.#relay' --impure
sudo nixos-rebuild switch --flake '.#flix' --impure
darwin-rebuild switch --flake .#mbp

Test configurations without switching:

sudo nixos-rebuild test --flake '.#<host>' --impure

Update flake inputs:

nix flake update

Clean up old generations:

./trim-generations.sh [--user|--home-manager|--channels|--system]

Cache

nix store sign --recursive --key-file ~/.config/nix/secret.key /run/current-system

nix copy --to 's3://nix-cache?profile=nixbuilder&endpoint=minio.nas.reinthal.me' /run/current-system
