Describe the enhancement

Use of CoreOS disk/boot images

And more explicitly, it's expected that many if not most users would continue to use the official Fedora CoreOS "boot images" (e.g. ISO, AMI, qcow2, etc.). This proposal does not currently call for exposing a way for a user to create the boot image shell around their custom container, although that is an obvious potential next step.

Hence, a user wanting to use a custom base image would provide machines with an Ignition config that performs e.g. rpm-ostree rebase ostree-remote-image:quay.io/examplecorp/baseos:latest as a systemd unit. It is likely that we would provide this via Butane as well; for example:

variant: fcos
version: 1.5.0
ostree_container:
  image: quay.io/mycorp/myfcos:stable
  reboot: true

Is this still being considered? I would love to see this feature
