----------------------------
Build your own custom Linux Kernel for SliTaz
Prepare your system

Install the slitaz-toolchain meta package. This package contains the required base files.
binutils
linux-headers
glibc-dev
gcc
make

# tazpkg get-install slitaz-toolchain

Install the packages required to configure and compile the kernel sources.
ncurses-dev
perl

# tazpkg get-install ncurses-dev
# tazpkg get-install perl

SliTaz provides a linux-source package. The kernel source tree will be downloaded from the mirror, installed to the /usr/src/linux-<VERSION> directory, and patched for SliTaz..

# tazpkg get-install linux-source
# /usr/bin/get-linux-source
# ls -l /usr/src
lrwxrwxrwx 1 root root 21 Jul 21 21:27 linux -> linux-2.6.25.5-slitaz
drwxrwxr-x 23 root root 4096 Jul 21 22:41 linux-2.6.25.5-slitaz
-rw-r--r-- 1 root root 48589640 Jul 21 21:28 linux-2.6.25.5.tar.bz2

Configure and Compile

The Linux kernel source tree is now ready to configure and compile.

Go to the directory that contains the kernel source tree.

# cd /usr/src/linux

Prepare the build from the default configuration.

# make oldconfig && make prepare

Modify the kernel configuration to your needs, and compile.
The menuconfig allows you to customise the kernel, which is built into the bzImage file. Any modules are built and then installed in to the /usr/include directory. You should then copy the kernel itself to the /boot directory.

# make menuconfig
# make
# make modules
# make modules_install
# cp arch/x86/boot/bzImage /boot

Configure the boot-loader (optional)

# leafpad /boot/grub/menu.lst

Add the new kernel to the list

# My kernel:
title SliTaz GNU/Linux (cooking) (Kernel <VERSION>)
root (hd0,1)
kernel /boot/bzImage root=/dev/sda2
