[CentOS] Replacing kernel-headers with custom compiled version (from kernel.org) - safe?
Hello CentOS users, Currently I have compiled kernel version 4.19.37, which the source is from kernel.org. I compiled the kernel by following steps: - get the kernel tarball and unpack it - install prerequisties as described in https://wiki.centos.org/HowTos/Custom_Kernel (in addition bc and openssl-devel) - copy the kernel configuration: $ cp /boot/config-3.10.0-957.21.3.el7.x86_64 ~/linux-4.19.37/.config - create configuration: $ cd ~/linux-4.19.37 $ make olddefconfig $ make nconfig - compile and create RPM package: $ make vmlinux $ make modules $ make rpm-pkg - install kernel RPM: # yum install ~/rpmbuild/RPMS/x86_64/kernel-*.rpm However, in the last step (installing kernel RPM), I got following notice: =============================================================================== Package Arch Version Repository Size ===============================================================================Installing: kernel x86_64 4.19.37_sentinel_custom-1 /kernel-4.19.37_sentinel_custom-1.x86_64 209 M kernel-devel x86_64 4.19.37_sentinel_custom-1 /kernel-devel-4.19.37_sentinel_custom-1.x86_64 817 M kernel-headers x86_64 4.19.37_sentinel_custom-1 /kernel-headers-4.19.37_sentinel_custom-1.x86_64 4.6 M replacing kernel-headers.x86_64 3.10.0-957.21.3.el7 Transaction Summary ===============================================================================Install 3 Packages There, the compiled kernel-headers package (4.19.37_sentinel_custom-1) is about to replace stock version (3.10.0-957.21.3.el7). Is it safe to continue installing from compiled RPM package above, or install kernel manually? Regards, Bagas

You may find the following article useful: https://kernelnewbies.org/KernelHeaders Akemi
