This is really awesome to hear, thanks a lot jzelinskie! Keep up the good work!

You are missing the point. It's not at all about Fedora itself here. What I was trying to say is that today CoreOS (even in) stable is using Linux kernel 4.14.32 (https://coreos.com/releases/) and therefore enabling deployments to use the latest and greatest features, performance optimisations and innovation from the Linux kernel community in enterprise environments. Going back to RHEL kernel would be a major step backwards preventing a wide user base from access to what CoreOS enables them to do today. I genuinely hope that CoreOS folks at RH don't give up on continuing to deliver this sort of innovation. That is all what I was trying to get across.

One of the main reasons we use CoreOS is that it ships stable and state of the art features from the latest Linux kernels, so features and infrastructure like eBPF are available and can be used without problems. RHEL kernels (e.g. speaking of RHEL7) on the other hand are ancient and heavily outdated, and only backport some of the newer features from upstream kernels, so user space making use of it cannot be run anymore preventing latest innovation (or killing Linux kernel innovation through supporting bypasses like DPDK).

Oracle's RHEL clone on the other hand ship their UEK kernel which is a recent, commercially supported kernel based on (almost) latest upstream. There, the situation is at least better than with native RHEL, but I truly hope Red Hat has an answer to that with brand new Linux kernel's on RH CoreOS side. Please don't let innovation coming from the kernel die by dictating ancient RHEL kernels to majority of users. CoreOS enables innovation, please make sure it continues to do so.

By the way, there was a good summary on this point with regards to RHEL kernel considered harmful here: https://medium.com/@sargun/red-hat-enterprise-linux-consider...
