Yes, it is very complex.

I don't want to see regular kernel messages, only irregular. So I use the "quiet" parameter.

While debugging enormous shutdown delays I found the solution with INIT_VERBOSE even
if it was not documented and only deep buried in /lib/init/vars.sh.

The point for this bug report was to just document this variable.
