For either(oneOf) types, we skip introspection as we cannot
determine which branch of the union was taken without more context
This *should* be safe, as it can currently mostly be triggered through
The `extraModules` setting of inventory modules.
Example:
```
importer.roles.default.extraModules = [
../../modules/nixos/common.nix
];
```
Error Message:

ClanLib
This folder is supposed to contain clan specific nix functions.
Such as:
- clan function
- select
- inventory function
- json-schema-converter
Structure
Similar to nixpkgs/lib this produces a recursive attribute set in a fixed-point.
Functions within lib can depend on each other to create new abstractions.
Conventions
Note: This is not consistently enforced yet. If you start a new feature, or refactoring/touching existing ones, please help us to move towards the below illustrated.
A single feature-set/module may be organized like this:
# ↓ The final clanLib
{lib, clanLib, ...}:
# ↓ portion to add to clanLib
{
inventory.resolveTags = tags: inventory.machines; # implementation
inventory.buildMachines = x: clanLib.inventory.resolveTags x; # implementation
}
Every bigger feature should live in a subfolder with the feature name. It should contain two files:
default.nixtest.nix- Everything else may be adopted as needed.

Testing
For testing we use nix-unit
