Comment 8 for bug 530829

I hadn't noticed that, Chris Coulsen. You're right, it's not installed by default from a Ubuntu CD.

The following includes my comments:

$ apt-cache rdepends policykit-gnome
policykit-gnome
Reverse Depends:
  xubuntu-desktop # depends, in universe
  gnome-mount # depends, in universe
  gnome-lirc-properties # depends, in universe
  policykit # suggests, in main

I installed all of those packages and ran polkit-gnome-authorization, and I only got five configurable settings: one under org.gnome.lirc-properties.mechanism and four under org.freedesktop.policykit.

To me, this means that polkit-gnome-authorization is practically useless and should be hidden. Users of Xubuntu at least will appreciate it.
