        Whether to enable k3b, the KDE disk burning application.

        Additionally to installing `k3b` enabling this will
        add `setuid` wrappers in `/run/wrappers/bin`
        for both `cdrdao` and `cdrecord`. On first
        run you must manually configure the path of `cdrdae` and
        `cdrecord` to correspond to the appropriate paths under
        `/run/wrappers/bin` in the "Setup External Programs" menu.
