Issue Description

The composefs backend in podman causes build failures after the images built:

mkcomposefs: Invalid integer 628
Error: creating build container: committing the finished image: failed to put layer using a partial pull: failed to convert json to erofs: exit status 1

Steps to reproduce the issue

On Fedora Rawhide install:

dnf install \
        podman \
        python3-dasbus \
        python3-paramiko \
        python3-podman \
        python3-pytest \
        python3-pyyaml \
        -y

Note: podman-5:5.0.1-1.fc41 and composefs-1.0.3-1.fc40 should be installed.

And build the BlueChi test container:

git clone https://github.com/eclipse-bluechi/bluechi.git
cd bluechi
podman build --build-arg copr_repo=@centos-automotive-sig/bluechi-snapshot -f ./tests/containers/integration-test-snapshot -t bluechi-image .

Describe the results you received

The podman build command fails due to mkcomposefs. For example (output from a CI run):

err: + podman build --build-arg copr_repo=packit/eclipse-bluechi-bluechi-885 -f ./containers/integration-test-snapshot -t bluechi-image .
