Hi Joe, Thanks for getting back to me.
I'm in an environment where I can't choose images of my choice, the only [relevant] ones I have available are CentOS 6 & 7 and RHEL 6 & 7. I know that Red Hat developed kpatch <https://en.wikipedia.org/wiki/Kpatch>; which enables hot-patching <https://en.wikipedia.org/wiki/Live_patching> of a running kernel. With CoreOS's FastPatch <https://coreos.com/using-coreos/updates/> I just need to join a non CoreOS host to a CoreOS cluster (it's easy to join etcd, then fleet follows via systemd [DBUS]). How would I go about setting up something similar with Project Atomic's ecosystem? Happy to contribute some elbow-grease!
