No need to do such magic. Just set logging up as you would normally.
The first logging instance should pick up logs from everywhere. For
example:
=== aurqt/aqds.py ===
class AQDS:
logging.basicConfig(format='%(asctime)-15s [%(levelname)-7s] '
':%(name)-10s: %(message)s',
filename=os.path.join(confdir, 'aurqt.log'),
level=logging.DEBUG)
log = logging.getLogger('aurqt')
console = logging.StreamHandler()
console.setLevel(logging.INFO)
console.setFormatter(logging.Formatter('[%(levelname)-7s] '
':%(name)-10s: %(message)s'))
logging.getLogger('').addHandler(console)
log.info('*** aurqt v' + __version__)
=== pkgbuilder/pbds.py ===
class PBDS:
logging.basicConfig(format='%(asctime)-15s [%(levelname)-7s] '
':%(name)-10s: %(message)s',
filename=os.path.join(confdir, 'pkgbuilder.log'),
level=logging.DEBUG)
log = logging.getLogger('pkgbuilder')
log.info('*** PKGBUILDer v' + __version__)
=== aurqt/__init__.py ===
from .aqds import AQDS
DS = AQDS()
import pkgbuilder # ← also imports pkgbuilder.DS = pkgbuilder.pbds.PBDS()
=== bin/aurqt output ===

=== {confdir}/aurqt.log ===
