## Playtime!
* [runtime default seccomp!](https://kubernetes.io/docs/tutorials/clusters/seccomp/)

What's Seccomp? 
https://docs.docker.com/engine/security/seccomp/

What capabilities do I have in unconfined?
What about docker defaults?
What about containerd?
capsh?
amicontained?

new feature gate that sets runtime default!
