Subject: [PATCH] Config files are installed with the .sample extension You can
 now do 'cp edge.conf.sample edge.conf' to create a n2n configuration. If the
 .conf (for edge and supernode) are present, the service is enabled
 automatically. This prevents unwanted services to be enabled, and it
 preserves services activation across updates
