Otherwise the old dictionary does. If 'new-defaults', a mapping should be given of the current defaults. Only if a value in ``old`` matches the current default, it will be updated with ``new``.

It also comments out that file by default. This is to be used by downstream modules (like dask.distributed) that may have default configuration files that they wish to include in the default configuration path. Parameters ---------- source : string, filename Source configuration file, typically within a source directory. destination : string, directory Destination directory. Configurable by ``DASK_CONFIG`` environment variable, falling back to ~/.config/dask. comment : bool, True by default Whether or not to comment out the config file when copying.

Double-underscores (``__``) in keyword arguments will be replaced with ``.``, allowing nested values to be easily set.

This goes through the following stages: 1. Clearing out all old configuration 2. Updating from the stored defaults from downstream libraries (see update_defaults) 3. Updating from yaml files and environment variables 4. Automatically renaming deprecated keys (with a warning) Note that some functionality only checks configuration once at startup and may not change behavior, even if configuration changes. It is recommended to restart your python process if convenient to ensure that new configuration changes take place.
