I was trying to find a kernel config for a recent kernel and I just noticed that the .config file is not being installed into /boot since the installkernel utility was recently changed. I have it installed with the following USE flags: [ebuild R ~] sys-kernel/installkernel-28::gentoo USE="grub systemd -dracut -refind -systemd-boot -uki -ukify" 0 KiB And the config file is at /usr/src/linux/.config, but it seems it is no longer installed into /boot: # make install INSTALL /boot Loading /usr/lib/kernel/install.conf… layout=grub set via /usr/lib/kernel/install.conf INITRD_GENERATOR (none) set via /usr/lib/kernel/install.conf.

I just noticed System.map is neither being installed
Yes that is a difference between Systemd's kernel-install (USE=systemd) and Debian's installkernel (USE=-systemd), see [1]. You can still get the config via various other methods: - /usr/src/linux/.config - /proc/config{,.gz} [1] https://wiki.gentoo.org/wiki/Installkernel
The manpage is misleading then :/ It says: In addition to that, System.map passed on the command-line is installed using the same logic. If the directory containing System.map contains .config file, it is also installed. If the directory containing zImage contains initrd file, it is also installed.

This is accurate (it is what Debian's installkernel does), but it does not apply to the +systemd case. The man page also says: If systemd’s kernel-install is present on the system and the environment variable SYSTEMD_KERNEL_INSTALL is set to 1, then it is called to install the kernel. The default setting for this environment variable is controlled by the ebuild. See the kernel-install manual for more information on how to configure it. And 'man kernel-install' says: COMPATIBILITY WITH THE KERNEL BUILD SYSTEM installkernel [OPTIONS...] VERSION VMLINUZ [MAP] [INSTALLATION-DIR] When invoked as installkernel, this program accepts arguments as specified by the kernel build system's make install command. The VERSION and VMLINUZ parameters specify the kernel version and the kernel binary. The other two parameters (MAP and INSTALLATION-DIR) are currently ignored. I'm open to suggestions to improve the wording in the installkernel manual though. It undoubtedly could be better.
(In reply to Andrew Ammerlaan from comment #4) [...] > I'm open to suggestions to improve the wording in the installkernel manual > though. It undoubtedly could be better. Maybe it could explicitly state that kernel-install won't behave as installkernel regarding the finally installed files (different files are installed, and they are also named in a different way), and that the details explained in the other paragraphs only apply to the Debian version 🤔
Better like this: https://github.com/projg2/installkernel-gentoo/commit/51da8dd3f418a113a8499367e3a2d9c6eaefd97e
It is nice now. Thanks a lot!
