Hi. I have a few "newbie" questions. This is a 2 part question which I was unable to find an answer. First, I have recently installed the kernel patch and video driver from Nvidia for my GeForce Ti 4800 video card for 3d on a fresh install of Redhat 8.0. I need to do all of the updates for Redhat. My question is, when I do the updates for the new kernels, will the kernel and video updates still be there, or will I have to reinstall them? Secondly, when I get an update for a new kernel, when I reboot, Grub lists the old and new kernels to boot from. Do I still need the old kernels, or can I delete them? Thanks.
