Bug#538709: Blame it in consolekit

[Roderich Schupp]

Plase reassign this bug to consolekit. Reasoning

I finally understand what's going on. In previous incarnations of g-p-m
the power button "worked" like this:

(1) hal listens for power button presses, tells g-p-m
(2) g-p-m listen for "power button pressed" notifications from hal
(3) g-p-m invokes a method on hal to shut the system down
(3) hal shuts the system down

The new sequence of operations is:

(1) g-p-m listens for an X button press event (key XF86PowerOff)
(2) g-p-m invokes a method on consolekit to shut system down
(3) consolekit shuts the system down

The first problem was (1): getting X to emit a "XF86PowerOff pressed" event.
This is solved with hal 0.5.13 which sets the necessary property on
/dev/input/eventX for the power off button, so that the X server will add it to
the list of input devices.

The remaining problem is (3): consolekit as present in Debian (0.3.0-3)
has been built without policykit and hence refuses to honor the
shutdown request.
Solution is easy: rebuild consolekit with policykit (just add libpolkit-dev to
Build-Depends) and don't forget to install its policy file. The default
policy (grant permission for shutdown to user at active console) should be fine.
