[SOLVED] understanding changes with new install kernel

[Dr_b_]

After updating to the new installkernal, attempted to upgrade to 6.7.2

Running systemd, with grub

however, make install now installs files like this:

Code: Select all

/usr/src/linux # make install
  INSTALL /boot
Loading /usr/lib/kernel/install.conf…
layout=uki set via /usr/lib/kernel/install.conf
INITRD_GENERATOR (none) set via /usr/lib/kernel/install.conf.
UKI_GENERATOR (none) set via /usr/lib/kernel/install.conf.
Loaded /usr/lib/kernel/install.conf.
MACHINE_ID=e2aba522d37f4762bed099449a92f594 set via /etc/machine-id.
Found cgroup2 on /sys/fs/cgroup/, full unified hierarchy
Found container virtualization none.
/dev/nvme0n1p1: Partition has wrong PART_ENTRY_TYPE=c12a7328-f81f-11d2-ba4b-00a0c93ec93b for XBOOTLDR partition.
Couldn't find an XBOOTLDR partition.
Failed to check file system type of "/efi": No such file or directory
Using EFI System Partition at /boot as $BOOT_ROOT.
Using entry token: e2aba522d37f4762bed099449a92f594
kernel version (6.7.2-gentoo) set via command line.
kernel image file (/usr/src/linux/arch/x86/boot/bzImage) set via command line.
Using ENTRY_DIR=/boot/e2aba522d37f4762bed099449a92f594/6.7.2-gentoo

so no longer do i get the typical :

Code: Select all

System.map-6.7.1-gentoo-r1*
config-6.7.1-gentoo-r1*
initramfs-6.7.1-gentoo-r1.img*

instead directories for loader, and the machine-id, within, which grub-cfg doesn't pick up

tried installkernel with and without systemd USE flag.

Is there a setting that can be made in installkernel config file to revert back to the default method

UPDATE: uninstalling kernelinstall, make install puts the files in the /boot dir correctly, run dracut as usual, creates correct initramfs, rename files vmlinuz and system map to match the current kernel version, and system boots ok

If you run
man installkernel you get

Code: Select all

INSTALLKERNEL(8)                              System Manager’s Manual                              INSTALLKERNEL(8)

NAME
       installkernel - install a new kernel image

SYNOPSIS
       installkernel version zImage System.map [directory]

DESCRIPTION
       installkernel  installs  a  new kernel image onto the system from the Linux source tree. It is called by the
       Linux kernel makefiles when make install is invoked there.

       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 con‐
       trolled by the ebuild.  See the kernel-install manual for more information on how to configure it.

       If  the new kernel is an unified kernel image, it is installed into {directory}/vmlinuz-{version}.efi.  Oth‐
       erwise, the new kernel is installed into {directory}/vmlinuz-{version}.  If a symbolic link  {directory}/vm‐
       linuz  already  exists, it is refreshed by making a link from {directory}/vmlinuz to the new kernel, and the
       previously installed kernel is available as {directory}/vmlinuz.old.

       In addition to that, System.map passed on the command-line is installed using the same logic.  If the direc‐
       tory containing System.map contains .config file, it is also installed.  If the directory containing  zImage
       contains initrd file, it is also installed.

BUGS
       installkernel resides in /sbin only because the Linux kernel makefiles call it from there.  It should really
       be in /usr/sbin.  It isn’t needed to boot a system.

Try

Code: Select all

SYSTEMD_KERNEL_INSTALL=0

in /etc/env.d/99no-systemd-kernel-install

tried installkernel with and without systemd USE flag.

Is there a setting that can be made in installkernel config file to revert back to the default method

Either:
- disable USE=systemd
- set SYSTEMD_KERNEL_INSTALL=0
- set layout=grub in /etc/kernel/install.conf

Note that emerge --config retains the environment from the initial emerge, so changing SYSTEMD_KERNEL_INSTALL (or disabling USE=systemd) has no effect on emerge --config. Unfortunately a full re-emerge is required.

Unfortunately a full re-emerge is required.

Do you mean of the entire system, or just installkernel?

Neither, a full re-emerge of gentoo-kernel is required, emerge --config retains the environment and is therefore not sufficient.

That being said, version 23 of installkernel should work better for you because it uses the "traditional" layout by default even when USE=systemd is enabled.

ohhh, i understand what you are saying now, using sys-kernel/gentoo-sources, and not gentoo kernel, the "emerge --config" and re-emerge didnt make sense

Code: Select all

# emerge -pv installkernel

# cat /etc/env.d/99no-systemd-kernel-install

# cat /etc/kernel/install.conf
layout=grub

make install:

Any suggestions?

It's a bit weird that the env var is not being picked up. Can you try:

Code: Select all

SYSTEMD_KERNEL_INSTALL=0 make install

Version 23+ of installkernel will use the more traditional layout even when USE=+systemd, so upgrading to this version should also fix your problem (and then you can remove /etc/kernel/install.conf, this should no longer be required).

[Dr_b_]

# emerge -pv installkernel
[ebuild R ] sys-kernel/installkernel-24::gentoo USE="-dracut -grub -systemd -systemd-boot -uki -ukify" 0 KiB

# cat /etc/kernel/install.conf
layout=grub
initrd_generator=
uki_generator=

# cat /etc/env.d/99no-systemd-kernel-install
SYSTEMD_KERNEL_INSTALL=0

This works:

Code: Select all

 /usr/src/linux # SYSTEMD_KERNEL_INSTALL=0 make install
  INSTALL /boot
 /usr/src/linux # ll /boot
total 197140
drwxr-xr-x 4 root root    12288 Dec 31  1969 ./

-rwxr-xr-x 1 root root   138046 Feb  2 15:38 config-6.7.3-gentoo*

i also exited/reloged into the shell after updating installkernel, and its now picking up the var correctly. ver24 is working fine, thanks for the help!
