+// In containerd, an image is merely the mapping of a name to a content root,

+// dictated by the type of the descriptor.
+//
+// From the perspective of this service, these references are mostly shallow,
+// in that the existence of the required content won't be validated until
+// required by consuming services.
+//
+// As such, this can really be considered a "metadata service".
