XDG_RUNTIME_DIR is actually only something I have discussed with a
couple of folks and implemented it because I needed it in
pam_systemd. However, there's no official documentation for it, nor have
I ever proposed it to the xdg mailing list, since there's a bit of a
uncertainty whether XDG_RUNTIME_DIR should be bound to the individual
sessions or to "first session to last session of a user".

I hope that at lpc/gnome summmit the folks involved can discuss this in
further detail so that we can agree on something and formalize it, and
send it to XDG. Until this happens nobody outside of systemd should use
this var.

It's a bit like XDG_SESSION_COOKIE, which is not official in any
way. While XDG_SESSION_COOKIE is probably going to go away sooner or
later, XDG_RUNTIME_DIR is something I definitely want to see documented
and starndardized.
