No,

but see this post:

http://groups.google.com/group/comp.lang.python/msg/851ce78e53812ade

It may lead you to more information. The thread shows that Sean
DiZazzo got logging working with the package.

I think you just have to pass the file object used by the handler
(fh.stream) in the files_preserve array.

i found a crude workaround:
i wrote a function in which i start logging after deamon starts

That seems rather sub-optimal; you'll be unable to use the logger for
anything before the daemon context opens. This kind of problem is
exactly what 'DaemonContext.files_preserve' is intended to address.

Hopefully you can make use of the 'DaemonContext.files_preserve' option
as intended; please see my message earlier in this thread.
