2.4.26-r6 to 2.6.7 kernel

tcma · Apprentice Joined: 28 Jun 2004 Posts: 208

I emerge gentoo-sources on emachines M6807 laptop and get 32 bit x86 2.4.26-r6 gentoo kernel.
If I want to get 32 bit 2.6.7 gentoo for my kernel, is the easiest way is to do:
emerge gentoo-dev-sources

Upgrading to 2.6.7 should not affect to my existing applications such as mozilla?
It should run as before, isn't it?

My disk partitions are as follows.
hda7 is free now,
so I can use it to install 2.6.7 and keep hda6 as 2.4.26.
May I use hda3 as boot and hda5 as swap for either 2.4.26 and 2.6.7?
Then I can select either 2.4.26 or 2.6.7 during boot.

Is this the procedure to install to hda7?
mke2fs -j /dev/hda7
mount /dev/hda7 /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/hda3 /mnt/gentoo/boot
cd /mnt/gentoo
...

tcma,

You many have as many kerenls in your /boot partition as yo have room for and choose which one to use in the grub boot screen. There is no need to make a new partition.

The new kernel should not affect any applications.

Build your second and subsequent kernels, just as you did the first kernel.

Be careful to use unique names when you copy the bzImage to /boot.
Using the name bzImage is not a good idea.

Add a new entry to grub.conf to allow you to choose and boot the new kernel.

Reboot and try it. If it fails, boot the old kernel and fix it.

Is this the best way to get 2.6.7?
emerge gentoo-dev-sources

tcma,

That will get you a source tree for 2.6.8-r4, on the basis of my last emerge sync, about a week ago. If you have a more recent sync, you may get a later kernel.

You then have to configure, build and install it.

nrh1703,

You will get a whole new kernel tree with its .config file missing.
If your old kernel is only a minor version or so away from the new one, copy the .config from the old tree to the new one.
In the new tree, run

make oldconfig saves a lot of time. just remember that you have to copy your old .config to /usr/src/linux before make oldconfig.
