Thanks.

PS : I add both rpm -q buildah and buildah version commands for the "testing" buildah image that works fine.

I am not sure if it possible to use overlay inside overlay, maybe use vfs when performing buildah build. i.e buildah --storage-driver vfs build ...

[giuseppe]

overlay on top of overlay is not supported.

[hiimheregit]

Indeed, changing the driver helped. Thanks for help @flouthoc @giuseppe
