I need to check if I have an usable polkit agent in a desktop-environment agnostic way.
Right now, what I'm doing is to check if a polkit agent is running, using a code like this:
ps aux | grep some-polkit-agent
some-polkit-agent may be:
polkit-gnome-authentication-agent-1(for gnome2 and gnome3-fallback)
The "no-fallback" gnome3 (gnome-shell) has its own polkit agent within the gnome-shell process itself, so I can't ps-grep it. What I assume is that if
gnome-shell is running then the polkit agent is in place.
The problem comes when a system has
hidepid enabled (see http://www.linux-dev.org/2012/09/hide-process-information-for-other-users/).
This security measure makes that a
ps doesn't show me any polkit agent running even if there is one.
Is there any better way that I can check for an usable polkit agent?
