It seems like Gentoo's kernel configuration is getting confused between `/boot` and `/efi`. Let's tackle this issue
step by step:
1. **Mount the EFI partition**:
First, you need to mount your ESP (EFI System Partition) which usually resides on `/dev/sdXY` where `X` is the
drive letter and `Y` is the partition number. For example, if it's an NVMe disk, it might be mounted as
`/mnt/gentoo/dev/mapper/your-lvm-name-sdXa1`.
You can mount the ESP manually by running:
```bash
mkdir -p /mnt/gentoo/boot/efi
mount /dev/sdXY /mnt/gentoo/boot/efi
```
Replace `/dev/sdXY` with your actual ESP partition device.
2. **Configure Gentoo to use /boot and not /efi**:
You can configure Gentoo to use the `/boot` directory for kernel boot files instead of the EFI partition by
modifying `/etc/fstab`. Add an entry like this:
```bash
LABEL="/boot/efi" /mnt/gentoo/boot/efi vfat defaults 0 2
```
This tells your system that the ESP should be mounted under `/mnt/gentoo/boot/efi`, but it's not where the
kernel is installed.
3. **Correcting `make menuconfig` and compiling issues**:
You might need to adjust some settings in the kernel configuration or even run a new build of the kernel to
ensure all dependencies are properly met.
To correct any issues with `make menuconfig`, ensure you've updated your `/etc/make.conf` file correctly,
especially if you're using multiple kernels. Also, consider updating the `kernel-config` package:
```bash
emerge --ask --verbose --update --newuse sys-kernel/kernel-config
```
4. **Update kernel source**:
It looks like your `/usr/src/linux` is not pointing to the latest kernel. You can use `eselect kernel` to list
and select different kernel versions, then update your source path accordingly:
```bash
eselect kernel list
# Select your desired kernel version
eselect kernel set <your-desired-kernel-version>
```
5. **Re-emerge the kernel**:
After making these changes, you might need to re-emerge the kernel package using the correct source path:
```bash
emerge --config '=sys-kernel/gentoo-kernel-6.12.54:6.12.54'
```
Remember, when dealing with kernel configurations and compiles, it's often helpful to start from scratch if you're
experiencing persistent issues or are unsure about specific settings.
**Additional Tips**:
* Make sure your kernel configuration is in sync with the Gentoo Handbook for kernel compilation.
* If you've been using a different kernel version previously, make sure all kernel modules and dependencies are
properly updated.
* For more advanced configurations like boot loaders (GRUB, rEFInd), it's crucial to have them correctly configured
to point to your new kernel location.
Hope these steps help resolve the issues.
>>> can not mount efi because kernel dotn have support. because of this i like to compile it again but to place it to /bo
... ot and not /efi.. how can we do that?
So, you want to recompile the kernel without EFI support, so that you can install it in `/boot` instead of relying
on an ESP (`/efi`) partition. Here's a step-by-step guide:
1. **Reconfigure the kernel**:
Before recompiling, ensure your kernel configuration is up-to-date and reflects your system's hardware. You can
use `make menuconfig` to interactively configure the kernel settings.
```bash
cd /usr/src/linux
make menuconfig
```
2. **Disable EFI support**:
Go into the "Boot Loader" section of the menu and find the option related to EFI (usually under "General
setup"). Ensure it's disabled.
3. **Save and exit**:
Save your configuration changes with a descriptive name, e.g., `custom-efi-disabled`.
4. **Recompile the kernel**:
Use the `make` command to recompile the kernel with your new configuration:
```bash
make -j$(nproc)
```
5. **Install the new kernel**:
Once compilation is complete, install the new kernel using the following command:
```bash
make modules_install install
```
6. **Update the bootloader (optional)**:
If you're using a traditional BIOS-based system with GRUB or another bootloader, you'll need to update its
configuration to point to your new kernel location in `/boot`.
7. **Mount /boot and copy the new kernel**:
Before unmounting the ESP (`/efi`), mount the root partition where you want to install the kernel (usually
`/boot`) and copy the compiled kernel there:
```bash
mkdir -p /mnt/gentoo/boot
mount /dev/sdXY /mnt/gentoo/boot # Replace with your root device
cp arch/x86_64/boot/bzImage /mnt/gentoo/boot/kernel
```
8. **Verify the kernel installation**:
After copying, verify that the new kernel is correctly installed in `/boot` by checking its presence and
permissions.
```bash
ls -l /boot | grep bzImage
```
9. **Boot with the new kernel**:
Finally, reboot your system to test the new kernel installation.
If everything goes smoothly, you should be able to boot from your newly compiled kernel in `/boot`, without relying
on an ESP (`/efi`) partition.
Remember to remove any unnecessary configuration files or backup old ones before proceeding. Also, make sure to
adjust your `make` commands according to your system's architecture (x86_64) and kernel version.
