[gentoo-user] Gentoo-kernel 6.6 -- how to install?

[Alexander Puchmayr]

Hi there,

Since now kernel 6.6 is stable, installation procedure seems to have changed.

I used to install it by

emerge --config gentoo-kernel
grub-mkconfig -o /boot/grub/grub.cfg

But grub does not find the kernel, since it is not installed in /boot's root
but in some uuid named sub directory.

Eselect news says for grub users, nothing changes, but actually it does not
work.

So how is this now supposed to work?

Best regards
Alex

I don't know what that does. I run make oldconfig; make; make modules-install;
make insstall. That's been my routine for years.

I can't help with grub - sorry.

Sounds like you have sys-kernel/installkernel-systemd installed, instead of
sys-kernel/installkernel.

I tried quite hard to follow the systemd way of installing kernels when
installkernel was split recently, but I gave up in the end and reverted to my
own way. For one thing, at boot time, the list of bootable kernels was far too
verbose to be useful. For another, the method involved too much error-prone
typing; not at all the unixy way.

Hey,
I've run into the same issue.

From what I could backtrack it was the merge,
of kernel-install into installkernel
(https://wiki.gentoo.org/wiki/Installkernel).

So what I did to fix was to add the following change,
as suggested in the wiki to prevent the systemd-kernel-install,
like:
```
$ cat /etc/env.d/99no-systemd-kernel-install
SYSTEMD_KERNEL_INSTALL=0
```
I am using grub, so maybe I am missing something the
systemd-kernel-install to work.


Regards,
Guillaume.

This means something was wrong before. The extra mkconfig step should
never have been necessary. All you should have installed is
installkernel[grub]. Following that, any 'emerge --config' on any
dist-kernel package ought to configure grub correctly.

Try installing installkernel with USE=grub and reporting what happens
when you try to config a dist-kernel.

HTH, have a lovely day!

I run grub. My flags...

[x8940][root][~] emerge -pv installkernel

[ebuild R ] sys-kernel/installkernel-18::gentoo USE="-dracut -grub -module-rebuild -systemd -uki -ukify" 0 KiB

After building the kernel, I usually run a script that includes...
the commands...

cp arch/x86_64/boot/bzImage /boot/vmlinuz-experimental
cp System.map /boot/System.map-experimental
cp .config /boot/config-experimental

WTF does this require a separate program now???
