I missed the note in the docs that the ignition config specified on `install-flatcar` will disable the `fetch` stage in ignition. This stage is required to read the user data ignition config from the metadata service. By moving our OEM ignition config to `oemfs/base/base.ign` it will always be merged with the user data config.
