Hi, I'd like to join the Atomic SIG. I am upstream author of one of the components (rpm-ostree), and have contributed to others like systemd, and SELinux, as well as work on packaging Kubernetes in http://copr.fedoraproject.org/coprs/walters/atomic-next/. I'm particularly interested in how we maintain the atomic host ostree composes and integrating it with the CentOS infrastructure.
