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

The polkit configuration in /etc overrides that shipped by packages in /usr/share.

  1. Create a file with the same content as in /usr/share/polkit-1/actions/org.freedesktop.udisks2.policy: cp /usr/share/polkit-1/actions/org.freedesktop.udisks2.policy /etc/share/polkit-1/actions/org.freedesktop.udisks2.policy

    Non cambie o ficheiro /usr/share/polkit-1/actions/org.freedesktop.udisks2.policy, os seus cambios serán sobreescritos pola seguinte actualización do paquete.

  2. Delete any actions you do not need from within the policyconfig element and add the following lines to the /etc/polkit-1/actions/org.freedesktop.udisks2.policy file:

      <action id="org.freedesktop.udisks2.modify-device">
     <description>Modify the drive settings</description>
     <message>Authentication is required to modify drive settings</message>
    <defaults>
      <allow_any>no</allow_any>
      <allow_inactive>no</allow_inactive>
      <allow_active>yes</allow_active>
    </defaults>
</action>

    Replace no by auth_admin if you want to ensure only the root user is able to carry out the action.
