Hi, i have downloaded a new kernel version(4.14) and built with Suse Linux, so kernel.rpm files gets generated. But i want to repack this newly built kernel with existing suse-linux.iso image. So, for this purpose i am using Mksusecd command :-

" sudo mksusecd --create new_ker.iso --addon kernel-4.14.175_94.41_default.x86_64.rpm -- SLE-12-SP4-Desktop-DVD-x86_64-GM-DVD1.iso ".

This command is creating a image file which has a new kernel as an add-on. While installation it is showing added add-on but it is not installing the new kernel . Installation proceeded with Old existing kernel in iso image.

Can anyone guide me how i can add a newly built kernel to the existing ISO image file so that i can install the new built kernel during the installation process of Suse-linux.

During the OS install, don't you have an option to select packages? If yes, what happens if you select your new kernel?

No, it doesn't have any option to select packages during OS installation.

Since you're using Suse Enterprise, have you contacted support?

No, i don't have support from Suse Enterprise. I am using it for evaluation purpose.

That's ok..since you have the demo, you get 30 days of support. Since you're choosing SLES, I'm sure their sales folks will be happy to do whatever they can to get you going.

Past that, have you thought about what you're doing? You're building a snapshot of the existing system...which has MULTIPLE KERNELS installed. Remove them from the system FIRST, then build the image.

Maybe it is better to ask in the offical SUSE Forum:
