Hi Aki,

as Lennard already told you in the GitHub issue that "last" just doesn't make sense in systemd, there is also no need to change the dependencies global for everyone. Especially as there are systems out there which doesn't have crond installed (because there are .timer).

Your best bet is really to change all your custom scripts from rc.local into proper .service and instead of crond check out systemd.timer.
