Hello all, It appears I've got two similar packages on my computer: - polkit, which is needed by the following packages : :: consolekit: requiert polkit>=0.94 :: devicekit-disks: requiert polkit>=0.94 :: devicekit-power: requiert polkit>=0.94 :: gconf: requiert polkit>=0.94 :: polkit-gnome: requiert polkit>=0.94 :: system-tools-backends: requiert polkit>=0.94 -policykit, which is needed by the following packages : :: hal: requiert policykit>=0.9-6 :: polkit-qt: requiert policykit :: pulseaudio: requiert policykit As noted on the forum ( http://bbs.archlinux.org/viewtopic.php?pid=644090#p644090), they do not reference the same policy rules. My guess is that policykit is due to be removed and replaced by polkit. But in the meanwhile the system-wide privileges are very difficult to manage ! Can someone tell me more about those packages ? What shall I do to have a functional privilege management ? Thanks for any tip, -Mathieu
