chore: get cooking with Live CD customizations
Not yet tested or built, but doing a snapshot for now. Also did a manual
update on the lockfile and some tweaks at Tailscale daemon CLI flags.

-
This repository contains NixOS and Home Manager configurations for various machines. The goal is to manage system and user configurations declaratively using Nix.
2
-
3
-
### Project Structure
4
-
5
-
The repository is structured as a Nix flake.
6
-
7
-
- `flake.nix`: The main entry point. It defines the flake's inputs (like `nixpkgs`, `home-manager`, etc.) and outputs. The main outputs are `nixosConfigurations` and `homeConfigurations`.
8
-
- `hosts/`: Contains the configurations for specific machines. Each subdirectory corresponds to a host and contains a `configuration.nix` file, which is the main configuration for that host.
9
-
- `shared/`: Contains modules that are shared across different hosts. This is where most of the configuration logic resides. These modules are organized into subdirectories based on their purpose (e.g., `desktop`, `server`, `home-manager`).
10
-
- `home-manager/`: Contains configurations for Home Manager, which is used to manage user-specific dotfiles and packages.
11
-
12
-
### Key Concepts
13
-
14
-
- **NixOS Modules**: The configurations are built using the NixOS module system. The `shared/` directory contains many reusable modules. When you need to add or change a configuration, you'll likely be editing one of these files or creating a new one.
15
-
- **Home Manager**: Home Manager is used to manage user-level configurations (dotfiles, packages, services). The main Home Manager configuration is in `shared/home-manager/main.nix`.
16
-
- **Flake Outputs**:
17
-
- `nixosConfigurations`: Defines the system configurations for different hosts. Each attribute in this set corresponds to a host.
18
-
- `homeConfigurations`: Defines user configurations that can be deployed with Home Manager.
19
-
- `exportedConfigs`: These are configurations that can be used by other flakes.
20
-
21
-
### Developer Workflow
22
-
23
-
#### Adding a new host
24
-
25
-
1. Create a new directory in `hosts/` for the new host.
26
-
2. Add a `configuration.nix` file inside the new directory. You can use one of the existing host configurations as a template.
27
-
3. Add a new entry to the `nixosConfigurations` in `flake.nix` for the new host, pointing to your new `configuration.nix`.
28
-
4. Import the necessary shared modules into your `configuration.nix`.
29
-
30
-
#### Modifying a configuration
31
-
32
-
1. Identify which module or host configuration you need to change.
33
-
2. Make your changes to the respective `.nix` file.
34
-
3. To apply the changes to a machine, run `sudo nixos-rebuild switch --flake .#<hostname>` on that machine, where `<hostname>` is the name of the host you want to update.
35
-
36
-
#### Updating dependencies
37
-
38
-
To update the flake's inputs (e.g., `nixpkgs`), run:
39
-
40
-
```bash
41
-
nix flake update
42
-
```
43
-
44
-
This will update the `flake.lock` file with the latest versions of the dependencies.
45
-
46
-
### Important Files
47
-
48
-
- `flake.nix`: The central point of the configuration.
49
-
- `shared/meta.nix`: Imports a base set of shared modules.
50
-
- `shared/home-manager/main.nix`: The main entry point for user-specific configurations managed by Home Manager.
51
-
- `hosts/<hostname>/configuration.nix`: The main configuration file for a specific host.
52
-
- `hosts/<hostname>/users/<username>.nix`: User-specific configurations for a given host, leveraging Home Manager. See `hosts/stellapent-cier/users/gildedguy.nix` for an example.
53
-
54
-
When working on this codebase, remember that it's all about declarative configuration. Instead of changing things imperatively on the system, you declare the desired state in these `.nix` files, and Nix takes care of making it happen.
