100% reproducibility is not guarenteed

[zouter]

A script is reproducible if you specify all inputs and outputs, use a docker, and fix the seeds.

However, it is quite easy to cheat this:

• Read some other files not specified in inputs
• Write some files not specified in outputs
• Use some other random number generator, e.g. random.org
• Use some input from the web

1. Is this problematic? Do we really need to guarentee 100% reproducibility?
2. Can we avoid this? Some ideas:
   • Only mount those files that are accessible, e.g. by creating soft links
   • Only include a network connection if some of the inputs are from the network (local or web)
