Ubuntu has had a different approach by having a second product name (Wily Werewolf, Xenial Xerus, Yakkety Yak, Zesty Zapus, etc.) which is also very unique. So in order to find out how to configure something in Ubuntu 16.10 I can look for: "Yakkety Yak smtp allow unsecure" and this will probably yield about 0 results from other Ubuntu versions.
Are you aware of a better idea than Ubunutu's one?
