This comprises most of my dotfiles, managed (mostly) by nix.

Quick Start

Build and Apply Configuration

# First install (if nh not yet available)
nix run nixpkgs#nh -- darwin switch

# Regular use (with NH_FLAKE set)
nh darwin switch                                              # Apply configuration
nh darwin switch --refresh --commit-lock-file                 # Update inputs and commit
nh darwin test                                                # Test without activation
nh darwin build                                               # Build without activation

# Cleanup
nh clean all                                                  # Clean old generations
nh clean all --keep 3 --keep-since 7d                         # Keep last 3 or within 7 days

Environment Variables

Set these in your shell or via the NixOS/home-manager module:

export NH_FLAKE="$HOME/path/to/flake"      # Auto-detect flake location
export NH_SHOW_ACTIVATION_LOGS=1           # Show activation output (useful for debugging)

Lima NixOS VM

# Start Lima VM
limactl start --name=default lima.yaml

# Build and apply NixOS configuration
lima -- nh os switch --refresh '#nostromo'
lima -- nh os test                          # Test without activation

Creating a Discrete Host Repository

To create a separate repository that consumes this flake for host-specific configurations (i.e., my work machine):

nix flake init -t github:roshbhatia/sysinit#discrete
