COS image will experience dev, beta, stable and LTS stage. Before LTS stage, image is named with its
family as a prefix, e.g cos-dev, cos-beta, cos-stable. However, the milestone
number in those families may change when channel promotions happen. Only when a milestone becomes LTS, the
image will have a new family, and the milestone number in the image name stays the same. The image

// "tcp" and "udp" networks does not listen for both IPv4 and IPv6
// connections. This is due to the fact that IPv4 traffic will not be
// routed to an IPv6 socket - two separate sockets are required if
// both address families are to be supported.
// See inet6(4) for details.
