Key Technologies

  • NixOS 25.05 - Declarative Linux distribution
  • Flakes - Reproducible builds with locked dependencies
  • Home Manager - Declarative user environment
  • Disko - Declarative disk partitioning
  • Hyprland - Modern Wayland compositor
  • NH (Nix Helper) - Modern rebuild tool with better UX

Common Commands

# Navigate to configuration
cd ~/dotfiles/thinkpad-p14s-gen5/

# Rebuild system
nh os switch                      # Modern method (recommended)
sudo nixos-rebuild switch --flake .#pop  # Traditional method

# Update dependencies
nix flake update

# Test changes
nh os test

# Validate configuration
nix flake check

# Clean old generations
nh clean all --keep 5

# Search packages
nix search nixpkgs <package-name>

Shell Aliases (configured)

  • rebuild → nh os switch
  • update → nix flake update && nh os switch
  • clean → nh clean all --keep 5
