 |
|
Howdy all,
Just did an emerge -u world today and noticed one of the items to be updated was my gentoo-sources from r5 to r6. This is my 1st time updating the kernel so wanted to keep -r5 in place just in case if I FUBARED my system. So this is what I did.
| Code: |
1. cd /usr/src/linux-2.4.20-gentoo-r6
2. Make menuconfig (Configured exactly like previous kernel -r5)
3. make dep && make clean bzImage modules modules_install
4. cp /usr/src/linux-2.4.20-gentoo-r6/arch/i386/boot/bzImage /usr/src/linux-2.4.20-gentoo-r6/arch/i386/boot/bzImager6
5. mount /boot
6. cp /usr/src/linux-2.4.20-gentoo-r6/arch/i386/boot/bzImager6 /boot
7. nano -w /boot/grub/grub.conf
8. added these lines to grub.conf:
title=Gentoo Linux Kernel r6
root (hd1,0)
kernel (hd1,0)/boot/bzImager6 root=/dev/hdb3
9. Saved grub.conf and umount /boot
|
To enable NVidia and ALSA sound in new kernel:
| Code: |
10. cp -R /lib/modules/2.4.20-gentoo-r5/video /lib/modules/2.4.20-gentoo-r6
11. cp -R /lib/modules/2.4.20-gentoo-r5/kernel/sound /lib/modules/2.4.20-gentoo-r6/kernel
|
Rebooted system then from Grub selected "Gentoo Linux Kernel r6". Kernel boots up fine and I have both ALSA sound and NVidia support in new kernel.
Please let me know if I will have any issues or if there is anything else I need to consider. Thanks for the info in advance.

you need to change the /usr/src/linux symlink to your current kernel, because there are packages that need the current kernel sources.
| Code: | $ cd /usr/src
$ rm linux
$ ln -sf linux-2.4.20-gentoo-r6 linux
|
that's it.

Thanks for the help pYrania! But..... This presents another question. I would like to setup the system so I can select the proper kernel to run via GRUB and then linux would boot under the selected kernel. But if I have to symlink to /usr/src/linux each time then reboot into linked kernel this can be a little pain in the tush. So is there anyway to automate this?
I know for the scenario I stated above this is probably overkill but eventually I would like to try out other kernel sources.
Any help or guidance will be greatly appreciated.

you just have to change this symlink if you're sure you'll stick with this kernel for a while. (or you're going to compile some packages depending on the kernel sources, eg. lm-sensors)
and no, there is no way to automate it.
