@lewismarshall take a look at this: https://kubernetes.io/docs/concepts/cluster-administration/sysctl-cluster/

[lewismarshall]

Unfortunately this is only for namespaced items:

Sysctls which are not namespaced are called node-level and must be set manually by the cluster admin, either by means of the underlying Linux distribution of the nodes (e.g. via /etc/sysctls.conf) or using a DaemonSet with privileged containers.

So I guess we either deploy bash or update the userdata with the "correct value" and test. It all comes down to if smiladon requires 'non-strict' filters or not... @vaijab

or update the userdata with the "correct value"

I prefer this, but for now this PR looks good. I am going to work on hardening host kernel with various MAC modules, etc and plan to stick all of that in userdata, but that's later.

Let's go with your changes first!
