Description

I use binder a lot for teaching short workshops (thanks nice people!) and when we use the shell via RStudio or Jupyter terminals, the default prompt is super long and ugly and takes up the whole screen:

jovyan@jupyter-ctb-2d2019-2dsnakemake-2ducdavis-2dv7l31369

so often the first thing I have people do in my workshops is reset the prompt with PS1='$ '. While this is straightforward enough, it finally occurred to me that hey, there's no reason this kind of thing couldn't be done in repo2docker (or somewhere else)! Hence this issue.

I'm not 100% sure what the prompt should be, but something shorter would be great. Heck, you could even turn it into a binder advertisement of sorts -- maybe make it jovyan@binder: or something!

Research direction
Look into the repo2docker Dockerfile and entrypoint scripts to find where the default shell prompt is set. Consider modifying the PS1 environment variable via a postBuild hook or directly in the Dockerfile. Ensure the change works for both RStudio and Jupyter terminals. Check existing files like 'postBuild' or 'apt.txt' for configuration patterns.
