NixDefinitions
NixDefinitions is a layer of NixOS modules that exposes a simple interface of a few options (e.g. what services to run, domain names), and turns that into a full description of all the systems that need to be running.
Where it's situated
NixConfigs
NixConfigs sets the few options exposed by NixDefinitions.
NixOS Instances & Services
The combination of NixConfigs and NixDefintions produces a detailed description of the Services and other system setup that should be running on the NixOS instances.
NixOps
NixOps consumes the combined NixConfigs/NixDefintions system description to know what the system should look like when deployed.
NixGuard
NixGuard compares the state of NixConfigs/NixDefinitions to the running state to detect inconsistent state and either fix or report it.
Purpose
NixDefinitions...
- simplifies the job of NixPanel, allowing it to not worry at all about how machines work, but simply produce a machine-readable translation of the options set by Administrators.
- factors out the system configuration that is common between any Fediversity system, defining a simple set of parameters that might differ between them.
