Creating Ubuntu 9.10 kernel package

 

1. Download and install the following required packages: fakeroot, kernel-wedge, build-essential, makedumpfile, kernel-package, libncurses5-dev.
2. Download the kernel source:

apt-get build-dep –no-install-recommends linux-image-$(uname -r)

apt-get source linux-image-$(uname -r)

 

          This will install the kernel source in the current working directory.

3. Enter into the kernel source directory:

cd linux-source-2.6.xx

4. copy config file from current installation

cp /boot/config-x .config

5. make oldconfig
6. make menuconfig, and modify kernel config options according to need.
7. Also make sure to disable CONFIG_DEBUG_INFO under “Kernel Hacking” in step 6 above. This ensures smaller size of resulting kernel package.
8. Make necessary changes to the source code.
9. export CONCURRENCY_LEVEL=, where X is the number of CPU cores in the system. This will ensure faster compilation.
10. make-kpkg clean
11. make-kpkg -initrd -append-to-version= kernel-image kernel-headers
12. This will create kernel-image-*.deb and kernel-headers-*.deb in the .. directory.
13. Install the kernel-image-*.deb and kernel-headers-*.deb using dpkg command:

dpkg –i kernel-image-*.deb

dpkg –I kernel-headers-*.deb

14. Boot into the newly installed kernel
