A network plugin with an invalid name does cause the atomic-openshift-node process to fail on startup.
Comment 2 Ben Bennett 2017-06-26 20:20:10 EDT
Since people can install arbitrary network plugins, we can't know it is invalid until the node attempts to run it.  The master doesn't use a network plugin (but we recommend that the master machine also have a node setup on it so the machine is part of the SDN).
