Only keeping the latest kernel is a Very Bad Idea. As is mentioned in other comments, Fedora keeps the three most recent kernels by default so that if anything goes wrong with the newest one, you have two backup kernels to use. Why? Well, when I updated to the 3.11 kernel, there was a problem with the video drivers and I couldn't boot into a GUI. I was, however, able to reboot, select the kernel I was using before the update and get everything working long enough to learn what the problem was and fix it. Without that backup kernel, I'd have been in Very Big Trouble.

For this same reason, I actually INCREASED the number of previous kernels that my desktop keeps.

you can find the setting in /etc/yum.conf the installonly_limit is what you want. You can read more about yum.conf by doing man yum.conf

I agree that it is probably better to keep older kernels in case of problems, and not a good idea to remove them because you don't like looking at more than one option in the menu. If the appearance of the menu is objectionable, it might be best to set the timeout to 0 so boot skips past displaying it at all.

That is a terrible idea! What do you do if the latest kernel doesn't boot and you can't get to the Grub menu to pick an earlier one? Keep booting and try to hit Esc fast enough? Having the menu visible for a few seconds is a small price to pay for the ability to pick whatever kernel works whenever you need.

or set it to 2 sec at least. it will work.

Installing a new kernel in Fedora does not tidy up the Grub boot menu. To accomplish what you want you should run

grub2-mkconfig > /boot/grub2/grub.cfg

as the root user.

You've updated your system (kernel) multiple times which is why you have multiple menu entries in grub. Get a listing of installed kernels using rpm -qa | grep kernel-3. and use yum remove kernel-[the ones you wish to remove] to clean-up the system.

As a guide:

rpm -qa | grep kernel-3. returns:




We only want to keep the one with the highest number (kernel-3.11.1-200.fc19.x86_64) which is the latest kernel.

Thus we'll run the command yum remove kernel-3.10.10-200.fc19.x86_64 kernel-3.10.11-200.fc19.x86_64 to remove the older kernels.

* As mentioned in other comments, keep at least the last known working kernel.

Method 2

yum install yum-utils

package-cleanup --oldkernels --count=2

Make the changes permanent while keeping backups:

vi /etc/yum.conf

Wonder how a -2 rated answer can be accepted as the right one. This is question is also very old.
