And this is why I only give Linux like one decade more to still be relevant on the server.
With hypervisors and managed environments taking over distributed computing, if there is a kernel derived from Linux or something completely different, it is a detailed that only the cloud provider cares about.
That doesn't really make sense in the context of docker.
It's still Linux inside the container. Even if it's some abstract non-Linux service thing running the container, what happens in the container is still the concern of the developer.
