* stop node upon receiving SIGTERM or CTRL-Ceven during genesis sleep by setting up interrupt before starting a node Closes #2434 * call Start, not OnStart when starting a component to avoid: ``` E[09-24|10:13:15.805] Not stopping PubSub -- have not been started yet module=pubsub impl=PubSub ``` being printed on exit
