I tried this recently with `kubectl cp` for my scratch image and it turns out that command will fail if the target container lacks a `tar` program in its PATH. I guess under the covers it's just doing a `kubectl exec <pod> -- /bin/tar ...` on the file rather than asking the kubelet to untar the file into the target container's filesystem.
