PostPosted: Thu Dec 21, 2023 10:39 am    Post subject: gentoo-kernel : call custom installkernel [SOLVED] Reply with quote

Hi!

I am testing gentoo-kernel and it does almost what I do manually, but I would like to install and name new kernel items using my custom install script.

I see in /usr/src/linux/scripts/install.sh that I can overwrite installkernel by using my scripts in ${HOME}/bin, but I tried to create a script in /var/lib/portage/home/bin and it is not called during emerge / install of gentoo-kernel: actual installkernel-gentoo is called. Also tried in /root/bin without success...

How can I define my custom installkernel script called automatically by make install ?

EDIT: SOLVED

from this post
Ionen wrote:
gentoo-kernel first merges the (stripped) sources alongside the kernel in /usr/src/, then in pkg_postinst() it'll call /sbin/installkernel (default provided by installkernel-gentoo) to copy the kernel to /boot, roughly the same `make install` would do.

This installkernel script itself runs any executable scripts in /etc/kernel/postinst.d/* with $1 being kernel version, and $2 path to the kernel.

These scripts can be used for whatever needed, grub setup, efi stub installs, cleaning or backing up old kernels/modules, etc... With a little work most things can be automated if not a too exotic setup, and with the new USE=dist-kernel even third party modules get rebuilt without user workarounds now :) (albeit need portage >=3.0.13 to solve a portage bug when multiple modules).


I simply add a postinstall hook to move versioned files to a my required folder, and remove what I don't need:
/etc/kernel/postinst.d/99-EFI.install:
#!/bin/env bash

ver=${1}

echo === CUSTOM SCRIPT
mkdir -pv /boot/EFI/gentoo
mv -v /boot/config-${ver} /boot/EFI/gentoo/config
mv -v /boot/vmlinuz-${ver} /boot/EFI/gentoo/bootx64.efi
rm -v /boot/*${ver}*


or for an ARM system (pinebook pro):
/etc/kernel/postinst.d/99-pinebook-pro.install:
#!/bin/env bash

ver=${1}

echo === CUSTOM SCRIPT
mv -v /boot/dtbs/${ver}/rockchip/rk3399-pinebook-pro.dtb /boot/
mv -v /boot/config-${ver} /boot/config-gentoo
mv -v /boot/vmlinuz-${ver} /boot/Image-gentoo
rm -vrf /boot/*${ver}* /boot/dtbs/


bonus: how to disable dracut
/etc/portage/package.use/gentoo-kernel:
sys-kernel/gentoo-kernel savedconfig -initramfs
sys-kernel/installkernel-gentoo -dracut
/etc/portage/profile/package.use.force/gentoo-kernel:
sys-kernel/gentoo-kernel -initramfs

I tuned in since I could probably utilize such feature, if possible. But meanwhile:

One place where you can customize the kernel name is kernel config itself. But that's only the name.
I have /etc/kernel/config.d/naming.config where I rename my kernel.

More advanced, although workaround, way would be to use /etc/kernel/postinst.d and place a script there which would then move and/or rename your kernel to your needs. Every script there will be run and given these arguments: <kernel version> <path to the new kernel>
From there it's pretty easy to construct a script to do whatever you want. I have my custom initramfs script there.

EDIT: Then there's the possibility the create your own installkernel script and ebuild which would then provide virtual of installkernel. :P

Thank you Zucca,

I will report on the progress in this thread, updating the OP when something is relevant.

Maybe the answer lies in gentoo/eclass/kernel-build.eclass at kernel-build_src_install()?

Finally, I will try with a post-install hook : move the versioned files from /boot to my preferred place

Finally, I use the hooks and it works
- one pre-install to disable dracut (which is forced for nothing, I don't use it and don't want an intramfs) : delete the dracut hook and replace it with a dummy script
- one post-install which moves the needed files to other locations (EFI, u-boot partition, other names...) and deleted unwanted files (initrd, unneeded DTBs for my ARM boards)

I will automate the deploy of those scripts in /etc/portage/bashrc (pre-install phase of gentoo-kernel) and it will be then too annoying 8)

I've set USE="-initramfs" for gentoo-kernel (because I use my own initramfs build script). Doesn't it work for you?

no, the USE flag is forced, and dracut is pulled by dependencies and called during installkernel
I will later re-check, I could have missed something...

At least it works and I don't need to manual reconfigure / build /kinstall the kernel on all my Gentoo installations :)

I do not see that flag as forced, and apparently Zucca does not either. What is the output of USE=-initramfs emerge --pretend --verbose sys-kernel/gentoo-kernel ; emerge --info for you?

Hi Hu,

I see it. This is profiles/base: Force sys-kernel/gentoo-kernel{,-bin}[initramfs], which is more recent than my last sync:

    profiles/base: Force sys-kernel/gentoo-kernel{,-bin}[initramfs]
   
    Add sys-kernel/gentoo-kernel{,-bin} to the entry forcing USE=initramfs
    on dist-kernels.  It was originally supposed to apply to all
    dist-kernels (i.e. kernels using generic config), and it was my mistake
    not to add new kernel packages to it.

You can override the force, which per the comment is done to make it difficult for users to build without the native initramfs support.

even with USE=-initramfs on gentoo-kernel, dracut is called because the hook in /etc/kernel.

I will try to see how to not set that hook (debianutils, USE="-dracut")

EDIT: USE="-dracut -initramfs" + -initramfs in package.use.force did the trick to disable and unmerge dracut :)

So.
I'd need to put following lines
Code:
sys-kernel/gentoo-kernel -initramfs
sys-kernel/gentoo-kernel-bin -initramfs
sys-kernel/vanilla-kernel -initramfs
... into /etc/portage/profile/package.use.force/dist-kernel to
    a) avoid pulling dracut as an depency
    b) avoid compiling and generating any stuff needed by initramfs creation process by dracut

... and hopefully things continue working as-is?

+ USE="-dracut" (for sys-kernel/installkernel-gentoo)

xaviermiller,

Thanks for summarizing you results!

Maybe for those finding this thread later you could add a quote from lonen in https://forums.gentoo.org/viewtopic-t-1128103-start-0.html
Quote:
This installkernel script itself runs any executable scripts in /etc/kernel/postinst.d/* with $1 being kernel version, and $2 path to the kernel.

This could be even included in the installkernel manpage, as there is no mention of scripts at all.

Personally, I wasted some time with the "executable" part...

xaviermiller,

with all the results we have here, I think it belongs to "Documentation". If you dont like it please tell me.

Moved from Kernel & Hardware to Documentation, Tips & Tricks.

For completeness and future reference, adding here the link to the new installkernel wiki page: https://wiki.gentoo.org/wiki/Installkernel

Also, overriding the USE=initramfs package.use.force is no longer necessary, nowadays instead of forcing the flag we print a big warning if it is disabled.
