 This is a small utility, typically used in conjunction with [Ignition][ignition], which reads metadata from a given cloud-provider and applies it to the system.
 This can include adding SSH keys and writing cloud-specific attributes into an environment file (e.g. `/run/metadata/coreos`), which can then be consumed by systemd service units via `EnvironmentFile=`.
