Updating fedora kernel
(Seems to happen more with a development release.) When it does happen, the older kernel is clearly highlighted in grub's boot menu, so I just cursor to the new kernel. I recently installed Ubuntu in dual boot with my Fedora and it messed up my boot menu.
This upgrades or installs the package currently installed to a newer version. After reboot make sure to check the version of the new kernel.
The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc. Base on the query information of the Kernel package that already install in this computer is 2.6.9-1.667 and the new package that already been download is kernel-2.6.11-1.14_FC3.i6866. kernel-2.6.11-1.14_FC3.i686selinux-policy-targeted-1.17.30-2.96.kernel-utils-2.4-13.1.49_FC3.i386selinux-policy-targeted-sources-1.17.30-2.96.policycoreutils-1.18.1-2.12.i386udev-039-10. FC3.7.i386rpm -Uvh kernel-2.6.11-1.14_FC3.i686udev-039-10. FC3.7.i386selinux-policy-targeted-1.17.30-2.96.policycoreutils-1.18.1-2.12.i386selinux-policy-targeted-sources-1.17.30-2.96.10. The kernel package contains the Linux kernel (vmlinuz), the core of the Red Hat Linux operating system.
Before Red Hat releases a kernel, it must first pass a rigorous set of quality assurance tests.
The Fedora Project has recently released stable version of Fedora 25.
Post update using dnf, a newer linux-image kernel may be installed; however, it normally should be taking over the older/previous kernel used.
