The data center is moving towards a container-centric world where the role of the host operating system becomes far more static and disposable. Modern configuration management tools (CM) solve some problems but create many more. Existing CM solutions with their complex abstractions and domain specific languages are built for servers with life spans of several months or years. In a container-centric data center the life span of a host operating system should last only as long as it can provide fundamental services without interruption (e.g. docker daemon, networking services, etc).
