New shutdown/reboot/logout dialog (transparent UI introduced in 13.04) doesn't proceed after a given time. So after running 'gnome-session-quit --power-off' in a script the user will have to press a button or the system will never shutdown.
In old dialog (<= 12.10) there was a countdown starting at 60sec which shutdown the system after ran out. This made it possible to shutdown a system automatically from command line without extra user interaction.
The dbus method which triggers the dialog indicate that there is such a function:
~$ qdbus org.gnome.Shell /org/gnome/SessionManager/EndSessionDialog
[...]
method void org.gnome.SessionManager.EndSessionDialog.Open(uint type, uint arg_1, uint max_wait, QList<QDBusObjectPath> inhibitors)
I'd expect 'max_wait' is seconds until proceed shutdown. But it doesn't work.
---------------------
I know there is an alternative with 'sudo shutdown -h now' and I also know how to make that sudo command password-less. But that would only work on my own system. I need this functionality for a OSS project where I don't want to mess around in users '/etc/sudoers' file. All other Desktop Environs I know have such a feature except Unity >= 13.04

Mh, I think it was a design decision not to do this... Actually to prevent this to happen we had to use some workarounds, so I think this is a Won't fix.
