With Fedora 38, I see the following error during installation that I did not see prior to applying your patch: cp: cannot stat '/boot/System.map-6.6.0-15157-gefb5302e6ea5': No such file or directory and when attempting to boot the newly installed kernel, I see: error: ../../grub-core/loader/efi/linux.c:47:kernel is too small. error: ../../grub-core/loader/efi/linux.c:47:kernel is too small. error: ../../grub-core/loader/i386/efi/linux.c:258:you need to load the kernel first. error: ../../grub-core/loader/i386/efi/linux.c:258:you need to load the kernel first. before I get kicked back to the grub menu. The /boot folder after installing the rpm package with your patch in it looks like: $ ls -al /boot total 240012 dr-xr-xr-x. 5 root root 4096 Nov 7 17:04 . dr-xr-xr-x. 18 root root 235 Nov 7 16:24 .. -rw-r--r--. 1 root root 268497 Nov 7 15:43 config-6.6.0-15156-g13d88ac54ddd -rw-r--r--. 1 root root 268497 Nov 7 15:50 config-6.6.0-15157-gefb5302e6ea5 drwx------. 3 root root 4096 Dec 31 1969 efi drwx------. 3 root root 50 Nov 7 17:03 grub2 -rw-------. 1 root root 114164610 Nov 7 16:26 initramfs-0-rescue-01cdbeade0ec4c07828d9f3919ec2772.img -rw-------. 1 root root 36334410 Nov 7 16:40 initramfs-6.6.0-15156-g13d88ac54ddd.img -rw-------. 1 root root 36174736 Nov 7 17:04 initramfs-6.6.0-15157-gefb5302e6ea5.img drwxr-xr-x. 3 root root 21 Nov 7 16:25 loader lrwxrwxrwx. 1 root root 42 Nov 7 17:04 System.map -> /boot/System.map-6.6.0-15157-gefb5302e6ea5 -rw-r--r--. 1 root root 8968631 Nov 7 16:40 System.map-6.6.0-15156-g13d88ac54ddd -rw-r--r--. 1 root root 8968631 Nov 7 15:50 System.map-6.6.0-15157-gefb5302e6ea5.old lrwxrwxrwx. 1 root root 39 Nov 7 17:04 vmlinuz -> /boot/vmlinuz-6.6.0-15157-gefb5302e6ea5 -rwxr-xr-x. 1 root root 14577352 Nov 7 16:25 vmlinuz-0-rescue-01cdbeade0ec4c07828d9f3919ec2772 -rw-r--r--. 1 root root 13012992 Nov 7 16:40 vmlinuz-6.6.0-15156-g13d88ac54ddd -rw-r--r--. 1 root root 0 Nov 7 17:04 vmlinuz-6.6.0-15157-gefb5302e6ea5 -rw-r--r--. 1 root root 13012992 Nov 7 15:50 vmlinuz-6.6.0-15157-gefb5302e6ea5.old That zero sized vmlinuz-6.6.0-15157-gefb5302e6ea5 is likely the cause of the grub error. It seems like this logic is likely still necessary for older distributions.
