For the nodes that are present in k.org, we should probably make up our
minds as to what needs to be the configuration. While I understand
incremental patches, please look through the list to make sure low
hanging items are addressed at the earliest. Commit message makes one

response makes me feel, that is probably not the case - it is hard to
distinguish between the two.
