Is systemd on or off topic here ?
From the wiki page - https://wiki.ubuntu.com/systemd#Warning.21_Experimental_code
Warning! Experimental code
systemd is under active development in Ubuntu although the rough plan would be to default to systemd during development of 15.04. If you want to help it's best to be running 15.04. (14.10 might be doable as well..)
I would think 15.04 is ubuntu +1 and thus off topic as per the FAQ.
