No .. none of the CentOS Kernels were EVER binary compatible with any RHEL kernel. CentOS Linux has always been (now also including CentOS Stream 8 and 9) a completely separate 'closed' build system. We use the SAME source code to build things, modified to remove branding. But CentOS has NEVER been (nor is any other rebuild distribution now) Binary Compatible. Want to see how .. just extract two rpms with the same name from two different distributions into separate directories and run a sha256sum on all the files in the different directories with find command. Some files may be identical (most text files that are copied), others will not be. It is virtually impossible for all produced packages to be 'binary compatible' UNLESS they are built with exact the same files (not files BUILT fromt he same sources .. the exact same files) in the build root AND with exactly the same software doing the building. Any group that claims 'binary compatibility' is either lying or they do not understand compiling and linking. CentOS never had that. Neither does any rebuild. This is why the CentOS Project 'CHANGED' our term from binary compatible to 'Functionally Compatible' a long time ago. (Using same source code, we produce DIFFERENT software .. that works the same way but has different SHASUM values. Don't be fooled by key words like 'binary compatible' .. check it out for yourself. If you build kpatches to kernels, to make them work you need to build the kpatch for the specific kernel (CentOS would need to build against CentOS kernels, etc). Also, there are the certificate signing issues and keys that you would need to take into account. You need to have the CA Trust to be able to create signatures that the system will allow. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
