+Update all components from kubernetes/kubernetes to that version.
+
+By default, replace statements are added for all Kubernetes packages,
+whether they are used or not.  This is useful when preparing a
+repository for using k8s.io/kubernetes, because those replace
+statements are needed to avoid "unknown revision v0.0.0" errors
+(https://github.com/kubernetes/kubernetes/issues/79384).
+
+With the optional -p flag, all unused replace statements are
+pruned. This makes go.mod smaller, but isn't required.
+
+The replace statements are needed for "go get -u ./..." which
+otherwise ends up updating Kubernetes packages like client-go to
+incompatible versions (in that case, a very old 1.x release which
+happens to have a "higher" version number than the current
+0.<Kubernetes minor version>.<Kubernetes patch version> numbers.
