01. Purpose

Defines and enforces reproducible system states across personal and server infrastructure. Ensures toolchain consistency and declarative package management.

02. Technical Stack

• Language: Nix
• Platforms: macOS (nix-darwin), Linux (NixOS)
• Framework: Flakes

03. Key Components

• Darwin Modules: macOS system and application configuration for macmini.
• NixOS Modules: Host and service definitions for the laptop and server, including Forgejo, Nextcloud, Immich, Jellyfin, and Vaultwarden.
• Home Manager: Shared user environment across macOS and Linux.
• Options Layer: Typed defaults in modules/options.nix, with per-host overrides.

04. Integration

Deployment via flake activation:

# NixOS
sudo nixos-rebuild switch --flake .#laptop
sudo nixos-rebuild switch --flake .#server

# macOS (after the first nix-darwin install)
sudo darwin-rebuild switch --flake .#macmini

First-time macOS installs use sudo nix run nix-darwin -- switch --flake .#macmini.

05. System Status

• Status: Archived — repository no longer maintained
• Hosts: macmini and laptop remain the active configurations; the server configuration is retained with its PDS disabled.
• PDS: Decommissioned 2026-10-01 after the account moved to eurosky.social.
