Fixing kernel updates not applying in Fedora 43

One of the stranger issues you can encounter on Fedora is when new kernels stop being bootable from the GRUB bootloader. This usually happens after major version updates, and has been reported online from Fedora 39 up to the present day. In my case kernels were being installed to /boot/efi rather than /boot, where GRUB expects kernels to be placed. In the process of fixing this issue, I learned about how Fedora and kernel-install determine where to place boot entries.
