One of the members of our team finds it more complex when it comes to diagnosing why things aren't running/starting as expected, but that's also down to the complexity we have around s6 with other setup scripts (we use it to manage the full suite of processes in our product).

Hence, they're not the biggest fan of it (and would talk negatively about it), but I _think_ s6 isn't really the culprit and instead the other complexity is.

Although, when things go wrong it can be a little bit harder to chase down than it was with our former manual "start this process" type scripts... But, you can just `./run` the run script which may tell you enough :-)
