 - The export of Nydus image and runtime (e.g. [docker](https://github.com/dragonflyoss/image-service/tree/master/contrib/docker-nydus-graphdriver), [containerd](https://github.com/containerd/nydus-snapshotter), etc.) is currently only supported on linux platform.
 - Nydus image layers cannot be mixed with other compression types in the same image, so the `force-compression=true` option is automatically enabled when exporting both Nydus compression type and other compression types.
+- Since the Nydus image layer does not correspond to the cache records, the inline cache export of Nydus image is unsupported.
 - Specifying a Nydus image as a base image in a Dockerfile is not currently supported (i.e. lazily pull using a Nydus image).
