Prerequisites

A memberlist key must be generated and stored inside the secret key management.

A pre-generated key ensures that the manifests can be applied multiple times without the secret key changing. Otherwise, elevated fail-over rates may occur during manifest application, as the speakers can not communicate during the rollout, due to differing keys.
