Comment 2 for bug 354137

The solution Martin implemented is working at least from version 0.146 which is present in jaunty repository.

Regarding how to identify when a system is running UNR, I agree on that it's unclear how to detect it. On one hand there's the possibility to check for some UNR-specific packages being installed, on the other hand checkbox may provide some hints if we rely on the fact that UNR will run only in some specific hardware.
