In above github project, in https://github.com/EarlRamirez/snipeit_iso/blob/master/isolinux/grub.conf file, there is ‘@‘ symbol for splashimage, and for kernel, @KERNELPATH@, @ROOT@, etc.

Will those be replaced by actual values? Where do actual values come from? How does actual values substitute those variables?

Thanks again,
