Is there a reason we got rid of the platform-specific logic (we had it for Orion and Acorn I believe) in setup.sh for loading modules, etc.? It facilitates consistency, and I just spent half an hour debugging a Python-related issue that would have been avoided if setup.sh had automatically set up env modules for me. It was an optional argument, so it doesn't impact anyone who doesn't want to use it. It would also be helpful on Acorn for setting TMPDIR in a way that accommodates login node and compute node installations.
