  <title>Disable repartitioning</title>

  <p><sys>polkit</sys> enables you to set permissions for individual
  operations. For <sys>udisks2</sys>, the utility for disk management services,
  the configuration is located at
  <file>/usr/share/polkit-1/actions/org.freedesktop.udisks2.policy</file>. This
  file contains a set of actions and default values, which can be overridden by
  system administrator.</p>

  <note style="tip">
    <p>The <sys>polkit</sys> configuration in <file>/etc</file> overrides that
    shipped by packages in <file>/usr/share</file>.</p>
  </note>

  <steps>
    <title>Disable repartitioning</title>
    <item>
      <p>Create a file with the same content as in
      <file>/usr/share/polkit-1/actions/org.freedesktop.udisks2.policy</file>:
      <cmd>cp /usr/share/polkit-1/actions/org.freedesktop.udisks2.policy /etc/share/polkit-1/actions/org.freedesktop.udisks2.policy</cmd></p>
      <note style="important">
        <p>Do not change the
        <file>/usr/share/polkit-1/actions/org.freedesktop.udisks2.policy</file>
        file, your changes will be overwritten by the next package update.</p>
      </note>
    </item>
    <item>
      <p>Delete any actions you do not need from within the
      <code>policyconfig</code> element and add the following lines to the
      <file>/etc/polkit-1/actions/org.freedesktop.udisks2.policy</file>
      file:</p>
      <listing>
<code>
  &lt;action id="org.freedesktop.udisks2.modify-device"&gt;
     &lt;description&gt;Modify the drive settings&lt;/description&gt;
     &lt;message&gt;Authentication is required to modify drive settings&lt;/message&gt;
    &lt;defaults&gt;
      &lt;allow_any&gt;no&lt;/allow_any&gt;
      &lt;allow_inactive&gt;no&lt;/allow_inactive&gt;
      &lt;allow_active&gt;yes&lt;/allow_active&gt;
    &lt;/defaults&gt;
&lt;/action&gt;
</code>
      </listing>
      <p>Replace <code>no</code> by <code>auth_admin</code> if you want to
      ensure only the root user is able to carry out the action.</p>
    </item>
    <item>
      <p>Save the changes.</p>
    </item>
  </steps>

  <p>When the user tries to change the disk settings, the following message is
  shown: <gui>Authentication is required to modify drive settings</gui>.</p>
