Configuration

Bootscript

Create the bootscript:

cat > /etc/rc.d/init.d/polkitd << "EOF"
#!/bin/sh
# Begin $rc_base/init.d/polkitd

. /etc/sysconfig/rc
. ${rc_functions}

case "${1}" in
        start)
                boot_mesg "Starting PolicyKit..."
                loadproc /usr/sbin/polkitd
                ;;

        stop)
                boot_mesg "Stopping PolicyKit..."
                killproc /usr/sbin/polkitd
                ;;

        restart)
                ${0} stop
                sleep 1
                ${0} start
                ;;

        status)
                statusproc /usr/sbin/polkitd
                ;;

        *)
                echo "Usage: ${0} {start|stop|restart|status}"
                exit 1
                ;;
esac

# End $rc_base/init.d/acpid
EOF
chmod -v 754 /etc/rc.d/init.d/polkitd

Link it into the runlevels:

for link in /etc/rc.d/rc{{0,1,6}.d/K29,{2,3,4,5}.d/S20}polkitd; do
  ln -sfv ../init.d/polkitd $link;
done

Privileges

PolicyKit installs desktop-console.privilege in /etc/PolicyKit/privilege.d which is the file that HAL will reference to see if the user can preform a specific operation (mount, cpufreq, hibernate, poweroff, reboot, suspend, etc...). Other privileges that manipulate a local device are most likely going to require this privilege.

There are a few ways to configure a privilege. You can allow anybody by setting Allow=uid:__all__, a specific user by setting Allow=uid:username, or a specific group by setting Allow=gid:groupname. The same applies for Deny.

The following command modifies the privilege file so that anyone in the users group is allowed to manipulate a local device:

sed -i "s/^Allow=.*/Allow=gid:users/" \
    /etc/PolicyKit/privilege.d/desktop-console.privilege
