Previously (or currently) CNI components can be - and are - encouraged to be installed on kube-system namespace:

$ helm template install/kubernetes/helm/istio-cni --name=istio-cni --namespace=kube-system | kubectl apply -f -

This way users can setup additional priorities for pod scheduling like system-node-critical.

With the istioctl manifest method, those components are installed in istio-system namespace.

Is there an way to install them in a different namespace like it's possible with helm?
