She credits runit and daemontools as inspiration, and it looks extremely similar. I hope that at some point she writes a comparison explaining what Nitro does differently from runit and why.

runit doesn't propagate SIGTERM to services it starts.
Hmm, is that desirable? If someone's going around sending SIGTERM to random processes they might also send SIGKILL, and there's no way Nitro can propagate SIGKILL to processes it starts.
It does, because SIGTERM is traditionally understood as the trigger for a shutdown. Docker - for instance - will send a SIGTERM to pid 1 when a container is stopped - which goes back to a previous comment here about using a real init as pid 1 if the thing in your container forks: https://news.ycombinator.com/item?id=44990092
It does if you use SIGHUP.
