Build your own custom Linux Kernel for SliTaz¶

author:	linea, fandesandro, jozee, seawolf, ernia, woodt

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
