You are not the first to be confused by that - it is almost a FAQ on the forum; however it is the expected behavior - yum will install the latest version of a package available and kernel-headers does not depend on the kernel version. You should be able to use "rpm -i --oldpackage ..." to install the version matching your kernel. Phil ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] applying kernel patch
I am a newbie and do not know as much in detail abt packages. However, I noticed something strange while installing gcc. I started with bare minimum 'no-base' install with a kickstart file, so I didn't have gcc in it. Later, when I installed gcc the 'kernel-headers' packages was marked to be updated to 2.6.18-128.1.10.el5 for dependency issues. Here is a summary: = Package Arch Version RepositorySize = Installing: gcc i386 4.1.2-44.el5 base 5.2 M Updating: glibc i686 2.5-34 base 5.2 M glibc-commoni386 2.5-34 base 16 M libgcc i386 4.1.2-44.el5 base 94 k Installing for dependencies: binutilsi386 2.17.50.0.6-9.el5 base 2.9 M cpp i386 4.1.2-44.el5 base 2.7 M glibc-devel i386 2.5-34 base 2.0 M glibc-headers i386 2.5-34 base 598 k kernel-headers i386 2.6.18-128.1.10.el5 updates 917 k libgomp i386 4.3.2-7.el5 base 67 k However, the kernel is 2.6.18-92.el5. The mismatch in kernel and kernel-headers is confusing me. Any insights? Thanks, CS.

Because it will potentially not run "as smooth" as the kernel version shipped by CentOS. While newer kernels typically improve hardware support, they also introduce changes that are incompatible with the userland utilities provided in CentOS, so these changes may actually *break* something that works with an older version... It's all part of what is called an "Enterprise Linux Distribution". When you choose such a distribution, you basically accept that some of your packages will be somewhat outdated (with backports for security issues) but on the other hand you know the components have been more tested together than with other "bleeding edge" distros...

Re: [CentOS] applying kernel patch
I am sorry for the miss understanding, I really agree to that too, but it is just that i thought you could have an alternative like the one I read in the http://www.howtoforge.com which actually just talked about downloading a vanilla kernel and applying your patch and them making an rpm version so you could run on other systems.
