In the logging package, the parameter disable_existing_loggers used in logging.config.dictConfig and logging.config.fileConfig does not apply to the root logger. More precisely, its disabled attribute remains unchanged (while it is set to True for non-root loggers). So it is either a bug or the documentation should be updated.
Illustration:
assert logging.getLogger().disabled is False
assert logging.getLogger("foo").disabled is False
assert logging.getLogger().disabled is False
assert logging.getLogger("foo").disabled is True
