Run manually and add for example --rootfs xfs, it works.

$ sudo podman run --rm --privileged -v /var/lib/containers/storage:/var/lib/containers/storage -v /home/fedora/fedora-bootc:/output --security-opt label=type:unconfined_t quay.io/centos-bootc/bootc-image-builder:latest build --type qcow2 --rootfs xfs --local quay.io/fedora/fedora-bootc:41
