Description: Candidates should be able to properly configure a kernel to include or disable specific features of the Linux kernel as necessary. This objective includes compiling and recompiling the Linux kernel as needed, updating and noting changes in a new kernel, creating an initrd image and installing new kernels.
Key Knowledge Areas:
◈ /usr/src/linux/
◈ Kernel Makefiles
◈ Kernel 2.6.x/3.x make targets
◈ Customize the current kernel configuration.
◈ Build a new kernel and appropriate kernel modules.
◈ Install a new kernel and any modules.
◈ Ensure that the boot manager can locate the new kernel and associated files.
◈ Module configuration files
◈ Awareness of dracut
The following is a partial list of the used files, terms and utilities:
◈ mkinitrd
◈ mkinitramfs
◈ make
◈ make targets (all, config, xconfig, menuconfig, gconfig, oldconfig, mrproper, zImage, bzImage, modules, modules_install, rpm-pkg, binrpm-pkg, deb-pkg)
◈ gzip
◈ bzip2
◈ module tools
◈ /usr/src/linux/.config
◈ /lib/modules/kernel-version/*
◈ depmod
In this tutorial we work with SUSE Enterprise Linux 11 SP3 using the kernel 3.0 and download the current latest stable release from kernel.org; being 3.13. We then run though the process are compiling the new kernel
1. wget “https://kernel.org/pub/linux…..”
2. tar -Jxvf linux-3.13…tar.xz -C /usr/src/
3. cd /usr/src/linux-3.13.5/
4. make clean
5. make mrproper
6. make oldconfig
7. make menuconfig
8. make bzImage
9. make modules
10. make modules_install
11. make install
12. reboot
