The application will auto-populate most fields based on the selected ISO. Customize Environment: Use the integrated virtual command line environment to customize the Linux filesystem. You can add/remove packages, modify files, and make other customizations. Select Kernel: Choose the kernel version to use when booting the new ISO Generate Custom ISO: Click Next to package your customizations into a new ISO image.
