 ## Deploy system categories
 
-This is also used in CI.
+We currently split out nixosConfigurations into these categories:
+
+- `system-ci`: Systems should be updated separately because they might break automated deployment processes.
+- `system-vm`: Virtual systems.
+- `system-physical`: Physical systems.
+
+You can roll updates with retries by category with:
 
 ```bash
-
-auto-deploy vm
-auto-deploy physical
+auto-deploy system-vm
+auto-deploy system-physical
