# Nora's Configs

The evolution of `nora/dotfiles`; Nix configs under `home-manager` deployed with `morph`.

## Deployment Host

On the depoyment host, I use nix channels, and set:

```
$ nix-channel --list
home-manager https://github.com/nix-community/home-manager/archive/release-22.11.tar.gz
nixpkgs https://nixos.org/channels/nixos-22.11
```

## Layout

These files are "organized" as follows:

- `common/` is the directory where most of the configuration happens.
  These are the files used in more than one host configuration, now or later.
    - `home_manager/` includes all common `home-manager` configs.
        - `fragments/` contains package and configuration sets for specific use cases
          For example, `home_manager/rust.nix` includes packages and options related to Rust development.
        - `common.nix` contains all configurations common across all `home-manager` deployments.
      For example, GPG agent configurations and Vim settings.
    - `users/` contains basic user definitions.
    - `default.nix` is the core file defining the default nix configuration for all machines.
    - `common.nix` contains all the common NixOS definitions that all machines will need.
    - `fragments/` contains small functions for configuring particular services or system aspects, like Syncthing
- `files/` contains files used by `home-manager` to deploy anything not covered by existing `home-manager` options.
- `hosts/` defines host-specific configurations for NixOS and `home-manager`.
    - `felonyspork/` is the bastion/external server (Lenovo Tiny)
        - `configuration.nix` is the core NixOS configuration file, copied from the installed system
        - `hardware-configuration.nix` is the hardware config, imported in `configuration.nix`.
        - `home.nix` is the `home-manager` config specifically for `felonyspork`.
- `ops/` contains all the information needed to deploy using `morph`.

The import structure goes as follows:

- The `ops/<network>/network.nix` file defining the hosts in a network imports
    - `common/default.nix` for all-machine defaults, which imports
        - `common/common.nix` for common setup, including fonts, nixpkgs setup, and locale, which imports
            - `common/users/*` which sets up usernames, shells, SSH keys, and groups for users.
    - the host's `hosts/<host>/configuration.nix` file, which configures NixOS on the host and imports
        - appropriate `common/fragments/<fragment>.nix` files, for specific services or use cases.
        - the hosts's `hosts/<host>/hardware-configuration.nix` file, which configures partitions and drivers.
    - the host's `hosts/<host>/home.nix` file, which configures `home-manager` for that host, by importing
        - `common/home_manager/common.nix`, which configures `home-manager` for all machines
        - various `common/home_manager/fragments/<fragment>.nix`, which configures a specific use case,
          like graphical programs or Rust development.

## Unconfigured

Currently, the primary dependencies are:

- DNS that sets the crimespoon and felonyspork names
- Mullvad VPN config on crimespoon, allowing LAN connections

## Deployment

Simply run `push`:

```sh
$ ops/home/push
```

To push to only a single machine, use `ops/home/push --on <machine>`.
