The polkit system daemon
' polkitd 'u polkitd
polkitd provides the org.freedesktop .PolicyKit1 D -Bus service on the system message bus . Users or administrators should never need to start this daemon as it will be automatically started by dbus-daemon (1) or systemd (1) whenever an application calls into the service .
polkitd must be started with superuser privileges but drops privileges early by switching to the unprivileged polkitd system user .
See the polkit (8) man page for more information .
Please send bug reports to either the distribution or the polkit -devel mailing list, see the link http://lists.freedesktop.org/mailman/listinfo/polkit-devel on how to subscribe .
