Yeah. Get a root shell at any Kubernetes *node* via `privileged: true` + `nsenter` sauce. PodSecurityPolicies will save us.

	#!/bin/sh
	node=${1}
	if [ -n "${node}" ]; then
	shift
	nodeName=$(kubectl get node ${node} -o template --template='{{index .metadata.labels "kubernetes.io/hostname"}}') \|\| exit 1
	nodeSelector='"nodeSelector": { "kubernetes.io/hostname": "'${nodeName:?}'" },'
	podName=${USER+${USER}-}sudo-${node}
	else
	nodeSelector=""
	podName=${USER+${USER}-}sudo
