755M root.squashfs# LiveISO

## Approach

- don't break into stages yet
- get megastage to work
- use isoinfo/coreos-installer iso ... to compare before/after
- testing testing testing
- integrate into cosa behind flag:
- https://github.com/coreos/coreos-assembler/pull/3861
- turn flag on in rawhide
- add to https://github.com/coreos/custom-coreos-disk-images
- and then look at breaking it into stages
- review PRs to Renata's fork
- https://github.com/ravanelli/osbuild/pulls

## To build with custom coreos-installer

1. hack on coreos-installer, `make`
2. build custom container:

$ cat Containerfile
FROM overridden
COPY coreos-installer /usr/bin/coreos-installer

3. build it:

podman build --from oci-archive:$(ls path/to/builds/latest/x86_64/*.ociarchive) -t localhost/fcos-with-newer-coreos-installer .

4. pass that new oci archive in your JSON file that gets fed to runvm-osbuild

## Stages
