  # By default, freeradius will generate Diffie-Hellman parameters and

  # - reproducibility (random generation)
  # - we don't want _anybody_ to use a cert where the private key is on our public binary cache!
  # - we don't want the certs to change each time the package is rebuilt
  # So let's avoid anything getting into our output.
