Hi,

This is working as designed. It's just that your usage is not correct. You are specifying two extra directories, one of which is /usr/lib/aarch64-linux-gnu/. That is, you are copying your local files under /usr/lib/aarch64-linux-gnu/ into the root directory in the image; /usr/lib/aarch64-linux-gnu/ is not a destination directory but an additional extra directory. The destination directory in the image is always /.

So for now, you have to prepare the right directory hierarchy in the configured extra directories. Please see https://stackoverflow.com/a/58661938/1701388 and #1581 to understand how the extra directories feature work.
