In CentOS 6.x/7.x and RHEL 6x./7.x, upgrading the Linux Kernel is a painful procedure which requires about a dozen steps. On Fedora, all it takes is a time-saving two-liner. You don’t need to concern yourself with the configuration of the grub boot manager, which is a frequent source of trouble on CentOS and RHEL.
