Updating Kernel in Hardy

Hardy(8.04) is a little different from all the other versions when building a kernel. Only Hardy has two packages for kernel installation: linux-image, linux-ubuntu-modules. If you do not install the latter one, your sound card and network card will can not be recognized.
Today, I built the kernel from the ubuntu source(not the original kernel source). So, I could use the including debian scripts for convenience. Here’s the steps:

1. Tools:

2. Sources:

The source will be downloaded in the current directory.

3. Customize:

cd into “linux-2.6.24” root.

I selected “core2” as my custom name.

Then patch some files:

*) debian/scripts/misc/getabis:
From: getall i386 386 generic server virtual
To: getall i386 386 generic server virtual core2

*) debian/rules.d/i386.mk:
From: flavours = 386 generic
To: flavours = 386 generic core2

4. Build:

If you get errors like:

Run the following command, it is issued by the Makefile:

5. Done:

My PC has a P4-2.6c CPU. It took about 90 minutes to finish. The kernel also consumed about 2G storage. After all, three *.deb files were generated:
*) linux-headers-2.6.24-27-core2_2.6.24-27.69_i386.deb
*) linux-image-2.6.24-27-core2_2.6.24-27.69_i386.deb
*) linux-image-debug-2.6.24-27-core2_2.6.24-27.69_i386.deb

6. Customize modules:

First, generate prepare scripts:

cd into “linux-ubuntu-modules-2.6.24-2.6.24”

Note: Custom modules name must match the custom kernel name, say “core2”.

Then patch some files:

*) debian/rules.d/i386.mk:
From: flavours = 386 generic
To: flavours = 386 generic core2

*) debian/rules.d/0-common-vars.mk (To prevent error in build step, debian/rules.d/3-udebs.mk):
From: disable_d_i = no
To: disable_d_i = true

Now generate new debian/control, which includes new custom kernel:

7. Build modules:

8. Done again:

This time, it took 30 minutes and consumed 300M storage. Two *.deb files were built:
*) linux-headers-lum-2.6.24-27-core2_2.6.24-27.45_i386.deb
*) linux-ubuntu-modules-2.6.24-27-core2_2.6.24-27.45_i386.deb

9. Install kernel:

Just double-click or install using the dpkg utility. Here’s my screen-shot:
