How to ask jupyterhub not to produce .ipynb_checkpoints?

I have no use of .ipynb_checkpoints so when I move the content out and there is always something that is leaving behind the directory that looks “empty” but rmdir just won’t do.

rm -r .ipynb_checkpoints/ is fine but I hate to do extra work.

This trouble won’t be there in the first place if this is not generated at all. I don’t like this checkpoints business.

This is handled by your singleuser server, not JupyterHub. Are you using JupyterLab?
