notebook option: change default cwd

[dcherian]

With the --notebook option, Jupyterlab thinks the directory with the notebook is the working directory. This is irritating because AFAICT, you can't navigate anywhere else. It also prevents saving a read-only notebook to a different file (I think this might be possible if I could change the working directory).

I notice that notebook-dir and notebook are mutually exclusive. Is it possible to relax that restriction?

Jupyterlab thinks the directory with the notebook is the working directory. This is irritating because AFAICT, you can't navigate anywhere else.

Unfortunately, this is the same reason notebook-dir and notebook are mutually exclusive. Say you launch Jupyter Lab server in /glade/scratch/bar and the actual notebook you want to work with is located in /glade/scratch/foo/notebook.ipynb. I don't think there is an existing workaround that would allow us to tell the jupyter server started in /glade/scratch/bar to navigate to /glade/scratch/foo/notebook.ipynb

Ah did some digging today: this looks like an upstream fix: https://github.com/jupyterlab/jupyterlab/pull/10667 . It's due to be released next week so we can revisit after that.
