# Infrastructure

Hello this is my new and improved Nix infrastructure.

## General layout

There are three main directories: 

- `secret`, which contains secrets
- `shared`, which contains shared config modules
- `system`, which contains the configurations for specific machines

I have some machines that don't run NixOS so I have separated the home-manager stuff (`home`)
from the NixOS system-level stuff (`core`).

For example, `thor` and `odin` are both NixOS machines, so for these machines, there is both
a `home.nix` for the home config of my user account, and a `core.nix` containing the 
system-level configuration of the machine.

### Shared configuration

NixOS and home-manager modules are used to organize the config.

A lot of config is shared between machines. This is stored within the `shared/` directory,
under either `shared/core/` for system-level NixOS modules or `shared/home/` for home-manager
modules.

There's also a shared key used by the `nix` user of each machine, for which the public key
is in `shared/data/`. This key is used to let other machines serve as remote builders.
