Hi,

I'm running into some issues with newer 3.12 kernels in Fedora 20 whereas everything is working fine with the older 3.11 kernels.

By default, Fedora seems to only keep 3 kernels. This is a great feature but I want the following kernel not to be removed: kernel-3.11.10-301.fc20

How can I force yum to keep an installed kernel and still be able to update in order to test new ones?

My question was very similar to question 10317. The only difference is that I don't want to skip kernel updates.

You can also change the install_only limit in /etc/yum.conf

Sure but I need to choose a very high number to be sure the kernel I want to keep will never be removed.

I found my answer here. I need to type the following command as a superuser to avoid automatic removing of the specific package kernel-3.11.10-301.fc20:

yumdb set installonly keep kernel-3.11.10-301.fc20

If I update the system after, I still get new kernel versions. Automatic removing of new kernels also still works using the installonly_limit value found in /etc/yum.conf.

If I want to revert the previous change, I can use this command:

yumdb del installonly kernel-3.11.10-301.fc20
