- A previous workaround done to recover from a panic on nil
ref is now not needed and removed. The issue was that I assumed
cli.Exit(err, int) was a way to exit; i.e. it uses os.Exit()
under the hood. However, it only constructs a struct that implements
error. Hence, we should return it, not just execute it.
- Also warn on root and Windows
- Move IPPool init to setup rather than run
