Running with multiple X sessions through systemd

[TLATER]

When starting a new X server I expect the editor to be opened in the same display as Chrome currently is. Instead, it seems to try opening an arbitrary display variable. Is there a way to export the DISPLAY variable from the Chrome window the command is called from?

Running multiple X sessions on different ttys, and I want to run the server as a systemd unit, so manually exporting DISPLAY is impossible until systemd supports launching X as a user unit without breaking the session.

Not sure there's a solution to this one, @TLATER. I'll think about it.
