Now we have a specific method on the Bootloader interface which tells Find() whether the specific bootloader is actually present on the current system. This will simplify future bootloader implementations to be able to return errors when identifying if a bootloader is present on the system is more complicated a question than just if the config file for that bootloader exists.
