# My NixOS configurations
Here's my NixOS/home-manager config files. Requires [Nix flakes](https://nixos.wiki/wiki/Flakes).
## Structure
- `flake.nix`: Entrypoint for hosts and home configurations. Also exposes a
devshell for boostrapping (`nix develop` or `nix-shell`).
- `lib`: A few lib functions for making my flake cleaner
- `hosts`: NixOS Configurations, accessible via `nixos-rebuild --flake`.
- `common`: Shared configurations consumed by the machine-specific ones.
- `global`: Configurations that are globally applied to all my machines.
- `optional`: Opt-in configurations my machines can use.

- `floki`: Lenovo ThinkPad X1 Carbon Extreme Gen 5

- `home`: My Home-manager configuration, acessible via `home-manager --flake`
- Each directory here is a "feature" each hm configuration can toggle, thus
customizing my setup for each machine (be it a server, desktop, laptop,
anything really).
- `modules`: A few actual modules (with options) I haven't upstreamed yet.
- `overlay`: Patches and version overrides for some packages. Accessible via
`nix build`.
- `pkgs`: My custom packages. Also accessible via `nix build`. You can compose
these into your own configuration by using my flake's overlay, or consume them through NUR.
- `templates`: A couple project templates for different languages. Accessible
via `nix init`.
## About the installation
Home-manager is used in a standalone way, and because of opt-in persistence is
activated on every boot with `loginShellInit`.
## How to bootstrap
All you need is nix (any version). Run:
```
nix-shell
```
If you already have nix 2.4+, git, and have already enabled `flakes` and
`nix-command`, you can also use the non-legacy command:
```
nix develop
```
`nixos-rebuild --flake .` To build system configurations
`home-manager --flake .` To build user configurations
`nix build` (or shell or run) To build and use packages
`sops` To manage secrets
## Secrets
For deployment secrets (such as user passwords and server service secrets), I'm
using the awesome [`sops-nix`](https://github.com/Mic92/sops-nix). All secrets
are encrypted with my personal PGP key (stored on a YubiKey), as well as the
relevant systems's SSH host keys.
On my desktop and laptop, I use `pass` for managing passwords, which are
encrypted using (you bet) my PGP key. This same key is also used for mail
signing, as well as for SSH'ing around.
## Tooling and applications I use
