Hello All, I purchased some Dell Latitude 3570 laptops. They came with Ubuntu preinstalled. ( Which I swapped for Centos7) I have to use Elrepo kernel on these machines to get some of the fn function keys to work. So I installed Elrepo's kernel-ml and selected this kernel with: # grub2-set-default 0 ( after disabling secure boot) The problem I see is that after a next kernel update, the new Centos kernel will be nr 0 and the machine will boot from that kernel if I tested this correctly. Is there a way I can enable elrepo kernel update but not the regular Centos kernel? Many thanks, J.
