WIP

Steps for fedora-coreos-config Git submodule update

To be automated via a GitHub Action:

• Bump submodule
• Create / delete symlinks to manifest-lock.overrides.arch.yaml files
• Run process-manifest-lock.py to update filtered lock-files

TODO

• Add manifest-lock.overrides.arch.yaml support to process-manifest-lock.py
