Yeah, you need to set some env vars currently. The idea however is that
the X/dbus libraries learn to look into XDG_RUNTIME_DIR on their own.

Nobody needs to wait for systemd --user exits. It will just exist in the
background as long as the user is logged in and will go away as soon as
he logs out entirely. It is refernce counted by the login sessions.

Yeah, starting it directly in the session is not really how we intended
it to be used, and it's problematic due to access to the cgroupfs. You
can make it work by manually granting yourself write access to the
cgroupfs subtree, but that's a hack for debugging purposes only.
