Well, too many difference between kernel 2.4 and kernel 2.6,
specially system library, glibc.

My sugeestion is just download Fedore Core 3 (2.6.9) and upgrade your
RedHat 9 to Fedora Core 3 (or Fresh installation).

http://download.fedora.redhat.com/pub/fedora/linux/core/3/i386/iso/

Regards,

Wesly

Luxana provide a good URL for your reference.
I checked the RedHat Linux 9 (latest patched from fedoralegacy) need to
installe:
-----
oprofile               0.5.3
xfsprogs               2.1.0

And upgrade:
-----
jfsutils               1.1.3
quota-tools            3.09
nfs-utils              1.0.5
procps                 3.1.13
glibc
-----
For kernel 2.6.x build

Just for reference to compare with directly upgarde to Fedoar Core 3.

COMPILING THE KERNEL USING GRUB!!
Go to http://www.kernel.org and download the 2.6.9 kernel
Change user to root
su
Copy the downloaded kernel to your /usr/src directory:
cp linux-2.6.9.tar.gz /usr/src/

Uncompress the kernel.
tar -zxvf linux-2.6.9.tar.gz

Change to the linux-2.6.9 directory
cd linux-2.6.9

Make mrproper (This will erase any .config file) This cleans out the configuration files and any object files an older version might have.
make mrproper

Complete configuration by one of these four options:
make oldconfig


This will ask you if you want to add in the new options from the kernel by selecting y/n/m.
make xconfig


(uses a GUI configuration) or
make menuconfig


(uses a terminal configuration based on curses) or
make config


You would need to edit the .config in order to select what options you want and then run make config to make the configuration file.

xconfig and menuconfig have a help option which is nice if you are unsure of what option you are turning on/off. make config and make oldconfig DO NOT have this help menu option.

Make the dependencies, which insures all things, like include files, are in place.
make dep

Make your bzImage
make bzImage

Make your modules
make modules

Copy the image over to /boot.
cp /usr/src/linux-2.6.9/arch/i386/boot/bzImage /boot/vmlinuz-2.4.19

Install the modules
make modules_install

Copy the new System.map over to /boot
cp /usr/src/linux-2.6.9/System.map /boot/System.map-2.4.19

Change back to the /usr/src directory
cd ..

At this point (for Red Hat) I remove the linux-2.4 symlink
rm linux-2.4

 
Then I make a new symlink to my new kernel directory.
ln -s linux-2.6.9 linux-2.6.9

Add the new kernel in the configuration file. For example, in grub.conf add:
title Red Hat Linux (2.6.9)
root (hd0,1)
kernel /boot/vmlinuz-2.6.9 ro root=/dev/hda2 hdd=ide-scsi


If your /boot is on its own partition please remove /boot part of the kernel location. Your last line in grub should read (If your /boot is on it's own partition)
kernel /vmlinuz-2.6.9 ro root=/dev/hda2 hdd=ide-scsi

Edit grub.conf
vi /etc/grub.conf

Add the new kernel in the configuration file

Example: grub.conf

title Red Hat Linux (2.6.9)
root (hd0,1)
kernel /boot/vmlinuz-2.6.9 ro root=/dev/hda2 hdd=ide-scsi

Reboot.

Hi,

   Just want to confirm with you that cat you really upgrade RedHat 9 to kernel 2.6.9?
Since this is PAQ and there are people may reference this solution later on.

   If you could provide your result will be helpful.
