Containerd snapshotter does not save layer chain id info in metadata.db for locally built image for platform other than host platform using docker buildx

Reproduce el problema con el comando docker buildx proporcionado y, después de compilar y eliminar la imagen linux/arm64, inspeccione metadata.db, content/blobs/sha256 y overlayfs/snapshots. Compare los casos local-build y registry-pull para determinar si la chain ID ausente y el contenido de las capas conservado son esperables o indican un error.

Description

We had built an image for platform linux/arm64 using docker buildx on amd64 machine.
We were unable to see the layer chainID information for this image in metadata.db from where we could find the linkage to the layer directory number in snapshots folder for that layer.
How should we corelate the layer chain ID info with snapshot directory number then?

Also when we do docker rmi -f ImageID , it does not remove the layer contents from content/blobs/sha256 folder also not from overlayfs/snapshots folder.

Reproduce

Build an image using Dockerfile
docker buildx build --platform linux/arm64 -t my-image .
docker images --tree (fetch the layer from config of the image)
open the metadata.db from /var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/metadata.db and search for respective layer chainID

Expected behavior

We were expecting the image layers chainID info in metadata.db before pushing it to registry just same as we get after we pull it from registry if same image is pushed.
