Comment 6 for bug 1652706

Just for the record (so nobody tries what I just tried in vain): Fedora Atomic 25(fedora-atomic-25-20170106.qcow2, MD5 sum e2e19eb37b5b026254410c38569d3649) gets the resizing bit right and generally works for the Kubernetes master, so that's something. Unfortunately the default /etc/sysconfig/etcd shipped with its flannel package doesn't match the expectations of
https://github.com/openstack/magnum/blob/master/magnum/drivers/common/templates/kubernetes/fragments/configure-kubernetes-minion.sh#L76 anymore: a few variables, such as FLANNEL_ETCD are missing, rendering the sed invocations in configure-kubernets-minion.sh and as a consequence the image useless for Kubernetes minions.
