This is the proper way to handle bootup output for the
console: request it and don't output ever time it's called
during boot....

Not perfect yet, some spots still taint the backend with
requiring relayd.inc which should only be included by the
plugin's own files directly.

When working on another plugin, I remembered why this was usefull ;)
