Building a New Kernel
- download source from kernel.org
- unpack source
- tar xvjf linux-2.6.26.tar.bz2
- create configuration (.config) file
- cd linux-2.6.26
- cp /proc/config.gz . (If this file does not exist, skip ahead to the alternate approach below.)
- gzip -d config.gz
- mv config .config
Alternate method of getting .config:
- If the file /proc/config.gz does not exist on your system, you can get the required file by issuing the following commands:
- yum install kerneldevel
- cp /usr/src/kernels/2.6.23.1-42.fc8-x86_64/.config ./
- make oldconfig
- customize your configuration
- make menuconfig
- compile kernel and modules
- make
- copy kernel image to /boot
- cp arch/x86/boot/bzImage /boot/vmlinuz-2.6.26
- copy system map to /boot
- cp System.map /boot/System.map-2.6.26
- install the modules
- make modules_install
- create initial ram disk image
- mkinitrd -k vmlinuz-2.6.26 -i initrd-2.6.26
- update GRUB
- vi /boot/grub/menu.lst
- reboot
