I do not know anything like enough to do anything more than comment, but
does the above indicate that the *-backend-systemd is being pulled in
as a result of an unhelpful dependency chain. And why does the
installation of libpolkit-backend-1-0-consolekit pull in
elogind libelogind0 libpam-elogind libpolkit-gobject-1-0-systemd
when consolekit has been installed in preference to elogind?
