SUMMARY = "containerd is a daemon to control runC"
DESCRIPTION = "containerd is a daemon to control runC, built for performance and density. \
               containerd leverages runC's advanced features such as seccomp and user namespace \
               support as well as checkpoint and restore for cloning and live migration of containers."
