Introduction to PolicyKit

PolicyKit is a framework for defining policy for system-wide components and for desktop pieces to configure it. It is used by HAL.

Getting the latest source

Note

This section is optional but recommended. You need this command only if you want to build the latest development version. If you install the latest development version of PolicyKit you'll also need to use the latest development version of HAL.

Check out the source from freedesktop.org:

git clone git://anongit.freedesktop.org/git/PolicyKit &&

It couldn't hurt to make a tarball so you have an unmodified source around for the future:

tar cvjf PolicyKit{-$(date +%Y%m%d).tar.bz2,}

Note

Replace "./configure" with "./autogen.sh" to build the latest development version.

Dependencies

Required

• D-BUS Glib
• Glib2
• Linux-PAM
• xmlto

Optional

• GIT (To get the latest source)
• Gtk-Doc

Configuration

Bootscript

Note

If you're installing the GIT Version of PolicyKit and HAL you do not need to install a bootscript for PolicyKit

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/polkitd
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

Note

The follow change is not needed if you're using the development version.

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
