policykit-1, consolekit, libpam-ck-connector, upower were all installed
already. What I don't understand is why the shutdown/reboot didn't start
working again when I reinstalled systemd, libpam-systemd and systemd-shim
(and rebooted). PID1 is init, and /sbin/init is not a symlink. Also,
libsystemd0 was not removed at any time.

What does fix it is to do something dimkr had me do when I was testing
alpha1 - rename/move /lib/systemd/systemd-logind. All the buttons work
after that.
