This repository keeps track of my personal NixOS configuration.

This setup use Flakes so the "entrypoint" is flake.nix.

The configuration directory contains configuration specific to the hosts:

• Configuration specific to sanctuary: configuration/sanctuary
• Configuration specific to atlantis: configuration/atlantis
• Default configuration for all hosts: configuration/default.nix

The modules directory is related to the programs or services optionally imported.

The [dev shells][dev_shells] file is related to development shells available on the system. For example, you can enter a dev shell with:

nix develop <path_to_repo>#rust

The archives directory is related to older files not used in the current configuration.

Rebuild the system from the local repository:

sudo nixos-rebuild switch --flake <path_to_repo>#hostname

Note that <path_to_repo> can be the path to the local repository but also the remote repository:

sudo nixos-rebuild switch --flake github:owner/repo#hostname

You can upgrade NixOS to the latest version by running:

nixos-rebuild switch --upgrade --flake <path_to_repo>#hostname

Note that auto-upgrade is enabled in configuration/default.nix.

The following command deletes old unreferenced packages and old roots, removing the ability to roll back to them:

nix-collect-garbage -d
sudo nix-collect-garbage -d

Note that gc.automatic is enabled in configuration/default.nix.

You can manually optimize the store using:

nix-store --optimise

Note that auto-optimise-store is enabled in configuration/default.nix.
