In our CI, we run kubekins image for most of the jobs. This is a debian image with upstart and does not enable systemd. So we should: * Bailout if any binary is missing other than systemd-run. * SupportsSystemd should check the binary path to correctly identify if the systemd-run is present or not * Pass the errors back to the callers so kubelet is forced to fail early when there is a problem. We currently assume that all binaries are in the root directory by default which is wrong.
