Rebuild Kernel CentOS

taken from Ron's email on the Misterhouse mailing list:

Build Kernel from source on CentOS 4.2 with latest updates:

Get depedencies:

1. yum install rpm-build kernel-devel.i686
2. yum install redhat-rpm-config.noarch ncurses-devel

Check kernel version:

1. uname -r

2.6.9-22.0.2.EL

Get source package:

1. cd /house/install
2. wget

http://ftp.nluug.nl/ftp/pub/os/Linux/distr/CentOS/4.2/updates/SRPMS/kernel-2 .6.9-22.0.2.EL.src.rpm

1. rpm -Uvh kernel-2.6.9-22.0.2.EL.src.rpm

Build source-code with all the RedHat patches:

1. cd /usr/src/redhat/SPECS
2. rpmbuild -bp --target i686 kernel-2.6.spec

Configure kernel:

1. cd ../BUILD/kernel-2.6.9/linux-2.6.9
2. ln -s /usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9 /usr/src/linux
3. make mrproper
4. cp /boot/config-2.6.9-22.0.2.EL .config

Optional change kernel name:

1. vi Makefile

EXTRAVERSION = -22.0.2.EL-CUSTOM

Use menuconfig to enable/disable any non-standard modules.. (here you can disable the HID drivers) If you don't plan to modify any settings, you can skip this step.

1. make menuconfig

Build kernel and modules:

1. make bzImage
2. make modules && make modules_install
3. make install
4. vi /boot/grub/grub.conf

default=1 -> default=0

Reboot and confirm new kernel is being used

1. uname -r

2.6.9-22.0.2.EL-CUSTOM
