We have a set of precompiled modules that we would normally (as in, Python on a local machine) advise users to load with a startup script pointed to by `PYTHONSTARTUP` in their shell profile. We would like to do something similar under TLJH, but as far as I can tell, `/etc/bash.bashrc` and `~/.bashrc` are not modifying the environment into which the iPython instances are launched. I understand that we can modify the environment for the application launchers with `/opt/tljh/config/jupyterhub_config.d/environment.py`, and that startup scripts can be added to `~/.ipython/profile_default/startup` for individual users, but we would like to have a startup script run for all users without having to copy it to each user’s home. Is there a recommended way to go about this? Thanks!

After experimenting some more (added `PYTHONSTARTUP` to `c.Spawner.environment`) it appears that the process started by the ‘Python 3 (ipykernel)’ launcher does not run the script pointed to by `PYTHONSTARTUP` as expected anyhow.
