Comment 11 for bug 1427654

As stated on the mailing list few months ago (https://lists.ubuntu.com/archives/ubuntu-devel-discuss/2014-December/015154.html), Ubuntu never offered a choice of init system, and won't start doing that. systemd is mandatory to be the supported ubuntu path. That's the reason why ubuntu-standard won't depend on systemd|upstart.

Note that for some kernel reasons, the Touch image is still using upstart, but that will change in the future.
