Good afternoon! I'd like to report a bug for `make install` on on the kernel. Steps to reproduce Attempting to run `make install` on the kernel in /usr/src/linux fails with the following scrollback: ``` morgans-revenge ~ # cd /usr/src/linux morgans-revenge /usr/src/linux # make -j50 CALL scripts/atomic/check-atomics.sh CALL scripts/checksyscalls.sh CHK include/generated/compile.h CHK kernel/kheaders_data.tar.xz morgans-revenge /usr/src/linux # make install sh -x ./arch/powerpc/boot/install.sh "5.15.145-gentoo-ppc64le" vmlinux \ System.map "/boot" + set -e + verify vmlinux + '[' '!' -f vmlinux ']' + verify System.map + '[' '!' -f System.map ']' + '[' -x /root/bin/installkernel ']' + '[' -x /sbin/installkernel ']' + exec /sbin/installkernel 5.15.145-gentoo-ppc64le vmlinux System.map /boot run-parts: executing /etc/kernel/preinst.d/50-dracut.install 5.15.145-gentoo-ppc64le vmlinux dracut[I]: Executing: /usr/bin/dracut --force --verbose --kernel-image vmlinux vmlinux/initrd 5.15.145-gentoo-ppc64le dracut[F]: Can't write to vmlinux: Directory vmlinux does not exist or is not accessible. * Failed to generate initramfs run-parts: /etc/kernel/preinst.d/50-dracut.install exited with return code 1 make: *** [arch/powerpc/Makefile:387: install] Error 1 morgans-revenge /usr/src/linux # ``` Dracut is version 060. I have been able to reproduce this with kernel version 5.15.135 to 5.15.145. I discussed on the IRC channel, here is a chat log of the discussion. ``` <matoro> JollyRoger: is your kernel image actually vmlinux or is it something else. i.e. do you actually have a vmlinux file in the root of your kernel directory <matoro> with genkernel at least it explicitly invokes "make vmlinux". maybe your kenrnel image is zImage or something like that? <awilfox> it's being called with the wrong arguments <awilfox> https://github.com/dracutdevs/dracut/blob/master/install.d/50-dracut.install <matoro> yeah but that's being called from /etc/kernel/preinst.d/50-dracut.install <matoro> which for us comes from sys-kernel/installkernel-gentoo <ernsteiswuerfel> sam_: ah, you already fixed my gcc-14 bug! that was fast :o <ernsteiswuerfel> but I got another one coming ;) <@sam_> uh oh <ernsteiswuerfel> no showstopper though ;) gcc-14 errors out with an an unknown opcode when building with -mcpu=7450. I am just waiting the build to finish with -mcpu=powerpc to check whether this helps <JollyRoger> Hi matoro, let me give it a try... if I try "file vmlinux" it returns to me this output: <JollyRoger> morgans-revenge /usr/src/linux # file vmlinux <JollyRoger> vmlinux: ELF 64-bit LSB executable, 64-bit PowerPC or cisco 7500, OpenPOWER ELF V2 ABI, version 1 (SYSV), statically linked, BuildID[sha1]=9f504ee96d83ed63d7fcfa8353cf627b7f05e969, with debug_info, not stripped <matoro> hmm, so it's there. what do you get for: $ qfile -v /etc/kernel/preinst.d/50-dracut.install <JollyRoger> Lemme try... <JollyRoger> Oh this is pretty neat! <JollyRoger> Thank you for showing me this, I will use this command a lot in the future, I just know it! <JollyRoger> morgans-revenge /usr/src/linux # qfile -v /etc/kernel/preinst.d/50-dracut.install <JollyRoger> sys-kernel/installkernel-gentoo-10: /etc/kernel/preinst.d/50-dracut.install <JollyRoger> This is what it gives me back in return. <matoro> okay, I'm kind of following what's happening <matoro> we have img=${2} <matoro> which is set to "vmlinux" <matoro> and then we have initrd=${img%/*}/initrd <matoro> this evaluates to "vmlinux/initrd" <matoro> but I don't think that's what we want, it should be just "initrd" <matoro> for example, if img=arch/powerpc/boot/vmlinux <matoro> then it evaluates to initrd=arch/powerpc/boot/initrd <JollyRoger> Oh. Hummm... any ideas on what we should try? <matoro> I believe you need to open a bug against sys-kernel/installkernel-gentoo <JollyRoger> I wonder what caused this to happen. <JollyRoger> Okay! <JollyRoger> I'll uh, I'll go and get it. <matoro> it's this PR's fault I think: https://github.com/projg2/installkernel-gentoo/pull/10 <matoro> looking at the change where this logic was ported from the eclass: https://github.com/gentoo/gentoo/pull/33727 <matoro> this is the original code: local image=${output%/*}/${rel_image_path##*/} <matoro> kind of hard to follow...do CC Andrew <matoro> this came in v8, so bug should specify: >=sys-kernel/installkernel-gentoo-8 <JollyRoger> Okay! I'll uh... I'll go and try to get a report drafted and sent in. I'll just search first to see if there's anything else there... <@sam_> i don't think there is, this is very new <@sam_> just get it filed <JollyRoger> Ooh. should I attach this chat log, or maybe a summary...? <matoro> can't hurt, most important thing is that you attach that log that you pasted <JollyRoger> Copied it all now! ``` Known workarounds: Nothing at this moment. Please let me know if there's anything I can do. Thank you! Peter. Reproducible: Always Steps to Reproduce: 1. Set directory to /usr/src/linux with `cd /usr/src/linux` 2. Run `make oldconfig && make -j50` or make to compile kernel 3. Run `make install` to install newly compiled kernel Actual Results: Dracut fails by being unable to write to vmlinux directory. Expected Results: Kernel image to be installed to /boot After discussing with matoro on the IRC channel, matoro suggested that this may be the issue: https://github.com/gentoo/gentoo/pull/33727

Though I don't have a powerpc machine to test it on, I'm pretty sure version 11 fixes the issue. Please reopen if this is not the case.
