Spun it up, noticed one other problem. Unfortunately, again, I'm not sure
if it's preexisting due to unfamiliarity. I stopped the bro topology (which was
successful), then I started it again. I got an error message about startup
failing. However, startup succeeded and things appeared to pick up normally.---
