Add an image *label* (e.g. label=*value*) to the image metadata. Can be used multiple times.
+Users can set a special LABEL **io.containers.capabilities=CAP1,CAP2,CAP3** in
+a Containerfile that specified the list of Linux capabilities required for the
+container to run properly. This label specified in a container image tells
+Podman to run the container with just these capabilties. Podman launches the
+container with just the specified capabilties, as long as this list of
+capabilities is a subset of the default list.
+
+If the specified capabilities are not in the default set, the container will
+print an error message and will run the container with the default capabilities.
