Running Qt GUI applications as root is dangerous. Some KDE applications are disabling being executed as root. For example, the next versions of Dolphin and Kate will show an error message and exit when started with root privileges. Polkit is the library made specifically to solve such problems. It is the standard framework used by Linux desktops to grant privileged actions to unprivileged processes. The goal of this project is to add Polkit support in KIO, the library used by KDE applications to manipulate the filesystem.
