In [Configuring Ray — Ray v1.9.2](https://docs.ray.io/en/latest/configure.html?highlight=default_worker.py#logging-and-debugging)  
it say:

You can also use `default_worker.py --temp-dir={your temp path}` to start a new worker with the given _root temporary directory_ .

what does it mean “you can use”, is default\_worker.py an external api?  
can we create our own workers?

Hmm maybe it is the legacy document that wasn’t deleted…
