Comment 60 for bug 1570472

Each release is getting a slightly different fix, unfortunately.

Zesty (4.8.2-3ubuntu1) is getting an adaptation of the Debian change which simply makes systemd the default on all Ubuntu and then switches back to upstart if it doesn't see /run/systemd/system (I will coordinate with the Debian maintainers to see if this is going upstream).

Yakkety has a version of my upstreamed change, so we just add 16.10 to the list.

Xenial is a much older codebase, but the minimal fix tested by a few folks via my PPA still applies and is what I have uploaded. It resembles the Debian and upstream fixes and is minimally invasive.
