I started a new Project today using your template.

I got almost everything working, going through the README.md, the only thing that fails ist the build disk image with the following error:

cannot build manifest: no default root filesystem type specified in container, please use "--rootfs" to set manually

Steps I did:

• Copy disk_config/iso-gnome.toml to disk_config/iso.toml
• Edit iso.toml: bootc switch --mutate-in-place --transport registry ghcr.io/pwfraley/lia-fedora:latest
• Edit: .github/workflows/build-disk.yml set BIB_IMAGE: "quay.io/centos-bootc/bootc-image-builder:latest" because the default ("ghcr.io/lorbuschris/bootc-image-builder:20250608") gives http error

Commit everything wait for the Build Container Image to finish

Start the Build Disk Image workflow, do not check s3 Platform amd64

Then the error comes in the step: Building artifact(s)
