The current kernel used by Red Hat in RHEL 4 is a 2.6.9-x kernel and it has 1973 patches. The one currently in use in RHEL 5 is a 2.6.18-x kernel with 2882 patches. Many packages are compiled against kernel-headers and depend on the proc structure that is there. SELinux is just one of many issues you will have if you try to use a main line kernel on CentOS. You will need to have several of the Red Hat patches (modified to work with the new kernel tree) incorporated in order to use a newer kernel on CentOS. If you absolutely have to have a newer kernel (you should not do this ... but hey, it IS your machine) ... then instead of trying to use a main line kernel, instead try to use the latest one from here: ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/RHEMRG/SRPMS/ This kernel has been tested for use with RHEL-5 and is 2.6.24-x. You still might have issues, but they should be far fewer than running a main line kernel on CentOS. Would you, if you boss told you he wanted you to, try to make the Windows Vista system files run on Windows 95?
