 This Home Manager Nix module (ai.nix) installs the Ollama package and configures it by reading a simple key-value configuration file (ollama.conf) for settings like the server host and default model. It sets environment variables (OLLAMA_HOST and OLAMA_DEFAULT_MODEL) for easy access in your shell or applications, with fallback defaults if the config file is missing or empty. Optionally, it also defines a user-level systemd service to automatically start the Ollama server on NixOS or systems with Home Manager’s systemd support enabled.
