 Every role has its own configuration options. Which are each listed below.

+??? Example
+    For example the `admin` module adds the following options globally to all machines where it is used.
+
+    `clan.admin.allowedkeys`
+
+    This means there are two equivalent ways to set the `allowedkeys` option. Either via a nixos module or via the inventory interface.
+    **But it is recommended to keep together `imports` and `config` to preserve locality of the module configuration.**
