I ended up copying those 3 files, manually: cp arch/arm/boot/zImage boot_install/vmlinuz-$KR cp .config boot_install/config-$KR cp System.map boot_install/System.map-$KR Regarding Fedora's version of /sbin/installkernel, if that's OK with Linus, who am I to argue. :-) On 2025-12-03 00:40, Dhaval Giani wrote:

Question for Fedora guys... How do you install kernel on your Fedora?
On Debian/Ubuntu, after compiling kernel, I usually do make zinstall INSTALL_PATH=boot_install and the 3 files (vmlinuz config, System.map) will be copied to "boot_install/" directory.
This is quite interesting - I compile kernels multiple times a day (for a living!) and I had neither seen zinstall, nor a common use of INSTALL_PATH. A little bit of googling tells me that on modern x86 make zinstall is the same as make install.
On Fedora, - it tries to copy to "/boot", which is not what I want. - it calls out to grub, which is also not what I want.
This is very interesting. Since I don't have my fedora system on hand immediately - I had to turn to gemini. The claim is, Debian (+derivatives) use /sbin/installkernel which respects INSTALL_PATH. Fedora on the other uses /sbin/installkernel which in turn calls kernel-install. This ignores INSTALL_PATH as per gemini. If true, IMHO this is a bug and should be reported upstream so that it can be fixed.
