Embarrassingly, I spent a lot of time wondering why my U2F was not showing and then I noticed this switch in the template. 

Most other rules shipped by void, use `plugdev`, and the current docs imply that it should be `plugdev`.
 
```
plugdev | Access to pluggable devices.
users | Ordinary users.
```
