Hence there is no trace in the log when a shutdown is triggered manually from userspace. This can make it hard to see sequence of events in the log when things go wrong, so make sure we always log a message when a shutdown is run. While there, clean up the logic flow so we don't have to continually check if the shutdown trigger was user initiated before logging shutdown messages.
