Thank you. Unfortunately, adding the additional PATH to this file doesn't fix the problem. 'grub2-mkconfig' finds the new kernel, but after that we get the problem with PATH for initrd. Fixed. After that I'm happy to get the new problem with 'invalid magic number' and 'you need to load the kernel first'. Hate it... I made it many times. The same steps. Now it's all brok... changed.

Hey, I'm trying to install the new vanilla kernel on tumbleweed.

Everything fine, I get vmlinux (not vmlinuz), System.map, etc.

Looking at /etc/grub.d/10_linux, it expects

case "x$machine" in xi?86 | xx86_64) klist="/boot/vmlinuz-* /vmlinuz-* /boot/kernel-*" ;;

In /boot I also have initrd.

By trying to update grub2 (by running 'grub2-mkconfig') I don't get any errors (return code 0), everything looks fine, but after that the new kernel is not listed in the config file. Does anybody can tell me what I miss?

I found a lot of documentation about SLE/openSUSE Kernel, but want to install new vanilla without any (open)SUSE-specific scripts, etc.

Thank you.

Cheers, Alex

Thank you, Larry! I think that was exactly the reason. I made all the steps as a normal user and just the last step as a user root. Both ('sudo make modules_install' and 'sudo make install') should be run as a normal user, i.e. not root. 'sudo make install' runs dracut and updates grub2 config. It seems there is no need to run 'grub2-mkconfig' at all... And yes, I installed 'kernel-install-tools' as you advised. @Andrei You're right, it seems, the last sudo-commad converts vmlinux to vmlinuz. Now it works. Thank you again guys.

Do you have package kernel-install-tools installed? For me, having that available runs the grub2 update with only the 'sudo make modules_install install' step.

By the way, building the kernel as root is really bad practice. Its Makefile is horribly complicated, and a simple mistake in it can ruin your system. At one point, such an error ended up trying to delete /dev/null. People that were building as root had their systems destroyed. Building without privilege just resulted in a trivial error. Only the install steps need to be run as root.
