Issue 1:
This is more of a question. Noticed this while testing out the AzureDisk volume plugin. mount on one of my nodes shows a lot of duplicated entries.

Is this expected, and if so, why?

If not, any idea the cause or resolution? Does it stem from running kubelet in container?

cc: @mikedanese as this is a kubernetes-anywhere deployed cluster. Any idea if this is expected?

The following is the sudo mount output from a node, after some flaky attempts at mounting an AzureDisk. Not that the mounts completely unrelated to the AzureDisk are also duplicated.

This is the sudo mount output from a fresh node in a cluster I deployed 10 minutes ago and has been sitting completely idle since. Note that it has a few of the /var/lib/kubelet lines repeated, but not nearly as many.

What you expected to happen:

The DNS and any self made pods to be created and stay alive.

How to reproduce it (as minimally and precisely as possible):

kubeadm init
kubectl apply -f https://raw.githubusercontent.com/romana/romana/master/containerize/specs/romana-kubeadm.yml
docker ps -a

Anything else do we need to know:

This is on a fresh install of Ubuntu 16.04 with upgrades applied to date. I followed the kubeadm setup guide.

Using Romana for DNS.
