       --modules=MODULES
	      Pre-load modules specified by MODULES.

	      Install only MODULES and their dependencies.  The default is to install all available modules.

       --directory=DIR
	      Use images and modules in DIR.

       --     All options after a -- will be passed directly to xorriso's command line when generating the image.
