This is an old and deprecated way to do this. You can also build using the src.rpm from here https://koji.fedoraproject.org/koji/packageinfo?packageID=8 run in /home/[your home] rpmdev-setuptree to create the rpmbuild heirarchy. Then run, as *user* (important) rpm -ivh [kernel*src.rpm] to install the src.rpm in the rpmbuild heirarchy. Edit the kernel.spec file and uncomment the #define line and add something like 20210727 to distinguish this kernel from repository kernel. Run rpmbuild -bp kernel.spec in the SPECS directory of the rpmbuild heirarchy to expand the src.rpm Switch to ~/rpmbuild/BUILD/kernel[]/linux[] Then cp a /boot/config-[] of a kernel to ./.config and run make oldconfig Then run makemenuconfig and make the changes to the kernel configuration that you want in your custom kernel. Save them. Then cp the .config file to a local config to override the defaults. cp ./.config ~/rpmbuild/SOURCES/kernel-local Switch back to ~/rpmbuild/SPECS and run rpmbuild -bb kernel.spec The output rpms will be in ~/rpmbuild/RPMS/x86_64. Run dnf -C install $(ls *.rpm) in that directory to install them. Seems complicated, but really isn't. If you are going to do this a lot, you could set up a screen instance to have access to all the directories needed just by using Ctrl-A [#] to make it easier. This does not sign the kernel so it can be booted via UEFI secure boot. So, you either have to turn that off in the BIOS when running it, or create your own signing key and sign it using pesign. I recommed the former for a one off. _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
