We use netboot to boot our RedHat Linux kernels. We usually use mknbi tool to create netboot image from Red Hat Linux kernel. However, I can't get this to work with the new Red Hat EL6 kernel.
One online document I found seems to say mknbi should not be used for Linux 2.6 or newer kernels any more, and wraplinux must be used. I downloaded wraplinux. However, I can't get this to work either. I can't find a clear document online to tell me how to use wraplinux to create a netboot image. I don't know what went wrong here.
I have been looking into this for quite a while. Please help if you can.
