Sure thing, add me as reviewer or ping me on IRC.

Sure, I just need a few pointers on where to put it please. I haven't
touched the main OpenStack docs yet.

Loggers receive log records then propagate to their parent logger and
send to any configured handlers. Handlers ask their formatter to format
the logrecord into a message then output the message. So by "file
logger", you mean "file handler". Handlers are unconfigured if the new
config doesn't include them, so both of those cases will work just fine.
Investigating this again, I have found an issue with logger levels -
