* Initial support for Flatcar Linux on Azure used the Flatcar Linux Azure Marketplace images (e.g. `flatcar-stable`) in https://github.com/poseidon/typhoon/pull/664 * Flatcar Linux Azure Marketplace images have some unresolved items https://github.com/poseidon/typhoon/issues/703 * Until the Marketplace items are resolved, revert to requiring Flatcar Linux's images be manually uploaded (like GCP and DigitalOcean)
