It’s been some time, but commit e7ad0d5 finally adds elogind support to
all the PAM sessions.  It does so by extending PAM with a procedure that
adds a session entry with pam_elogind.so to all the PAM service.

This extension mechanism for cross-cutting PAM concerns is implemented
in 12c00bc.

I’ve confirmed that ‘loginctl’ now knows about logged-in users and
seats.  I haven’t check what effect it has on GNOME and Xfce but
feedback would be welcome!
