It's not how I interpret "reload" and how "reload" was traditionally
implemented by initscripts. "reload" means - request daemon to do
whatever is necessary to start using new configuration. It never
implied changing this configuration. This happens outside of scope of
performing "reload" action. You seem to interpret "reload" as request to
update static on-disk configuration of service. Am I right?
