In this case they only should need to define the releases they support and not specify any additional locations. Later they may determine that they only need to replace packages, or one other file they should not be required to code every location for each release</div><div class=""><br class=""></div><div class="">Also, at the same time we MUST clean up importing various yaml files. Specifically, tasks, volumes, node roles, and network roles. Requiring that they all be maintained in a single file doesn't scale, we don't require it for tasks.yaml in fuel library, and we should not require it in plugins. We should simply do the same thing as tasks.yaml in library, scan the subtree for specific file names and just merge them all together.
