 |
|
I have been trying to install the bin kernel on my new gentoo install but I cant figure out where it is getting installed. It looks like its not being placed in /boot
I am not using a separate /boot partition and i mounted my efi
This is my fstab:
| Code: | UUID=FA26-3B1F /boot/efi vfat fmask=0137,dmask=0027 0 2
UUID=857d36cd-ab31-4349-a875-9ba45c15e276 / btrfs subvol=/@gentoo,noatime,compress=zstd 0 0
UUID=41c9da3b-d044-434b-b853-c18170bd4040 swap swap defaults 0 0
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0 |
| Code: | # eselect kernel list
Available kernel symlink targets:
[1] linux-6.12.16-gentoo-dist *
(chroot) tux / # eselect kernel set 1 |
| Code: | # installkernel
layout=uki set via config
INITRD_GENERATOR (dracut) set via config.
UKI_GENERATOR (dracut) set via config.

MACHINE_ID=292fed8dc0094343a8bd9e6c3d5cb98c set via /etc/machine-id.
Found cgroup2 on /sys/fs/cgroup/, full unified hierarchy
Found container virtualization none.
Directory "/boot" is not the root of the file system.
Couldn't find an XBOOTLDR partition.
Failed to check file system type of "/efi": No such file or directory
File system "/boot" is not a FAT EFI System Partition (ESP) file system.
Using EFI System Partition at /boot/efi as $BOOT_ROOT.

Kernel image not installed to '/usr/lib/modules/6.12.16-1-lts/vmlinuz', requiring manual kernel image path specification. |

It looks like it thinks that /boot/efi is the /boot directory and it is complaining that my efi partition is not a FAT EFI partition. Not sure what it complains about as in my efi partition is working properly for another distro. |

It is being installed where your configuration is telling installkernel to install it. layout=uki combined with your partition setup, combined with using systemd's kernel-install, means that the kernel (or actually a UKI) goes in the \EFI\Linux directory of the EFI System Partition (ESP). You have the ESP mounted at /boot/efi, so full pathname as seen by your booted operating system is /boot/efi/EFI/Linux.
You must have had the systemd and uki USE flags set when package sys-kernel/installkernel was installed. If this result is not what you wanted, you need to adjust your configuration or USE flags. Are you actually building a Unified Kernel Image (UKI)?

I was actually just trying to install the precompiled kernel. So I did remove the uki flag and rebuilt installkernel but still its installing the kernel in /boot/efi/EFI/Linux/292fed8dc0094343a8bd9e6c3d5cb98c-6.12.16-gentoo-dist.efi
It is actuall ynot even generating an initrd.I jsut want it to install intraframs and kernel in /boot

Also remove the systemd USE from it as well. That is what is creating the specified path. |

Are you using systemd? Are you wanting to boot with GRUB?

Then, in a file in /etc/portage/package.use:
| Code: | | sys-kernel/installkernel dracut -systemd |
if prefer to run grub-mkconfig yourself, or:
| Code: | | sys-kernel/installkernel dracut grub -systemd |
if you want to have grub-mkconfig run automatically every time you install a new kernel.
And, in either case:
| Code: | | # emerge --oneshot sys-kernel/installkernel |
afterwads.

| You probably want to clean up your ESP by deleting the unwanted files. |
