Removing old kernels?

carlosinfl · 04-12-2005, 09:44 AM

I noticed that my kernel has been updated 3 times since it was installed a few months ago. I know how to remove the "Grub" entries from the list but I was wondering if I can or even should remove the old kernel versions that I am no longer using.

I would assume this would keep my Linux system a bit cleaner or less cluttered with having 10 old kernels that are no longer used.

I know it is good to keep the last kernel just in case I need to revert back to it for fail safe reasons.

Thanks for any info.

You can remove the entries by deleting them from your /boot/grub.conf. This method keeps your old kernels in /boot, so if you want to completely uninstall the old kernels and grub entries, do

Code:

$rpm -qa | grep -i kernel

A list of installed kernels will be shown and to remove them just do

Code:

#rpm -e kernel-version
