+# This YAML file shows how to deploy the CSI snapshotter together
+# with the hostpath CSI driver. It depends on the RBAC rules
+# from rbac-csi-snapshotter.yaml and rbac-external-provisioner.yaml.
+#
+# Because external-snapshotter and external-provisioner get
+# deployed in the same pod, we have to merge the permissions
+# for the provisioner into the service account. This is not
+# necessary when deploying separately.
