Hi, everyone
I'm a very new to Linux. I'm using Red Hat 8.0 with Kernel 2.4.18.
Now I want to try new Kernel 2.6, But I don't know how to update or patch the Kernel. So is there some one who can guide me for patching new Kernel.
Also I want to know that new Kernel 2.6 has all bugs fixes and enhancement from 2.4.18 or should I go for increamental update?
Thanx in Advance

In the future, please try to make better and more descriptive titles. Thanks.

If you want to go from 2.4.18 to 2.6.0, unfortunately it would probably be less hassle to just download the latest to compile, instead of patching as you would have to patch to 2.4.19, then 2.4.20 and so on up to 2.6.0.

There are many tutorials regarding compiling the kernel. ex. www.tldp.org has a howto on it.

The basic steps are if downloading the tarball, not sure about RPM, I don't use RPM's and never done a kernel compile/install using them, I'd stick to source:

Download the tarball and unpack it in your /usr/src directory.

Create the symlink to your newly created directory called linux-2.6.0 like this:

cd /usr/src
ln -s linux-2.6.0 linux

Now you can cd into linux and it will take you to /usr/src/linux-2.6.0

I never do this step but you can do a 'make mrproper' but I don't think its really necessary for the latest kernel.

Then you want to configure your kernel, if your in X you can do a 'make xconfig' for the GUI config. I prefer to use 'make menuconfig'.

After configuring the kernel how you see fit, save and it will exit.

Now do this to build the kernel:

make

And then to create the kernel image:

make bzImage

If you opted to have modules, you will want to do:

make modules
make modules_install

You can find your kernel in the /usr/src/linux/arch/i386 directory for you to move or copy to your /boot directory.

for redhat, i recommend that you use their custom-built kernels since they are designed to do special things within the redhat system

their custom kernels are available from the redhat security and errata section of their site, but i'm not sure if they have released a 2.6 kernel

however, i know that redhat has been backporting a few features and improvements from the 2.6 kernel down to their 2.4 kernels

since they are available in rpm's, they are simple to install

Thanks for your reply. I will remember in future for meaningfull title. But one thing you left in your reply that is it nececessary to update every version of patch or simply directly update to 2.6.0
Thanx
