Thanks for the heads up.   We&#x27;re rebuilding some infrastructure now.  We would have defaulted to building on 14.04, but this gives us reason to switch to 15.10.   That&#x27;s a change I&#x27;ve been wanting to make for a long time anyways, but I was waiting for 16.04 LTS.   Yesterday a major portion of our site was down for a few minutes because an `service nginx reload` silently failed because upstart had lost track of the process.   I assume that sort of thing wouldn&#x27;t happen with systemd because it uses cgroups.
