Items to discuss:
- This is a complicated issue with many parts.
- Mention Bash startup: What does a non-prompt non-login interactive shell mean.
- MPI startup: non-login interactive shells.
- Lustre and MDS and finding a module.
- ibrun passing of the environment
- Why unguarded module commands are a problem
- Why TACC makes the module command a no-op when on a compute node.
