A superfree distribution which I won't touch because it's based on Debian/Ubuntu and therefore has systemd.
Instructions on getting Lubuntu (desktop) working for the CubieTruck.

I don't know if this version of Lubuntu, or whatever it turns into when updated, has systemd. I'm going to say no because 14.10 is so damned old.
It's an official project by Ubuntu to maintain something lighter.
It works well, and I've had a significant history with it.
