Dear buildah community,

we are just trying to create a container image inside an unprivileged container using buildah, however this process fails as shown below:

$ buildah bud -f Dockerfile --format docker -t $IMAGE_NAME

'overlay' is not supported
            over overlayfs, a mount_program is required: backing file
            system is unsupported for this graph driver

any idea what we are doing wrong?

thank you
