We have actually 3 polkit agent implementations in Portage: gnome-extra/polkit-gnome lxde-base/lxpolkit sys-auth/polkit-kde-agent
I guess a virtual is required. Just a simple example, gnome-extra/nm-applet requires a polkit auth agent (not present in RDEPEND atm -- bug!) in order to handle wifi passwords, etc. But the same applet can be used in both GNOME and LXDE, making lxpolkit a better choice over polkit-gnome for the latter. My proposal is to create a virtual pkg listing all the polkit auth agent implementations and make pkgs depend on it. -- Fabio Erculiani
