Running 17.04 (Zesty Zapus) and trying to start an upstart script but I noticed it's not getting executed. Then I noticed that upstart isn't even listed as an installed package even if there are lots of scripts in
/etc/init. Apparently they are not run since introducing a typo in e.g cron doesn't affect its startup.
How should I run the upstart script? Install upstart or run it through some systemd-layer? Does installing upstart break something when the other scripts in
/etc/init are suddenly run?
