The helper tool had a very early check whether the automatically created CA key/cert are available and thus it would abort if the key was unavailable even though we don't need or even want to have the CA key. Unfortunately our NixOS test didn't catch this, because it was just switching from a configuration with an automatically created CA to a manual configuration without deleting the generated keys and certs. This is done now in the tests and it's also fixed in the helper tool. Reported-by: @jpotier Signed-off-by: aszlig <aszlig@redmoonstudios.org>
