The new installkernel application that is now included in systemd-udev package allows installation although destination files are already present in the boot directory of the kernel package, but is failing with the implemented workaround for the old installkernel application from grubby package.
For the new installkernel application, as Davide says: <<The %post currently does a shuffling dance before calling installkernel. This isn't actually necessary afaict, and the current implementation ends up triggering downstream issues such as https://github.com/systemd/systemd/issues/29568 This commit simplifies the logic to remove the shuffling. For reference, the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post section to create initramfs and grub hooks").>>
But we need to keep the old behavior as well, because the old installkernel application from grubby package, does not allow this simplification and we need to be backward compatible to avoid issues with the different packages.
Mimic Fedora shipping process and store vmlinuz, config amd System.map in the module directory instead of the boot directory. In this way, we will avoid the commented problem for all the cases, because the new destination files are not going to exist in the boot directory of the kernel package.
Replace installkernel tool with kernel-install tool, because the latter is more complete. Suitable manual actions are added as a default if tool is not present (unusual).
This paragraph should be reworded, and the corresponding code should be fixed.
This patch works for fedora 38 and fedora 39, but may break openSUSE tumbleweed, at least.
The kernel-install itself does not copy files, but invoked scripts in /usr/lib/kernel/install.d/
In Fedora,
/usr/lib/kernel/install.d/20-grub.install
copies those files to /boot/.
In openSUSE, the 'udev' package provides /usr/bin/kernel-install, but /usr/lib/kernel/install.d/20-grub.install is missing.

In openSUSE with the udev package installed, none of vmlinuz, config, System.map is copied to the /boot directory.
Applying the following on top should fix the regression, although I did not test any other RPM-based distros.

V1 -> V2:
- Complete to be backward compatible with the previous installkernel
application. V2 -> V3:
- Follow the suggestions from Masahiro Yamada and change the installation
V3 -> V4:
- Make the patch applicable to linux-kbuild/for-next (ia64 support was
already removed).
