| 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
- wget “https://kernel.org/pub/linux…..”
- tar -Jxvf linux-3.13…tar.xz -C /usr/src/
- cd /usr/src/linux-3.13.5/
- make clean
- make mrproper
- make oldconfig
- make menuconfig
- make bzImage
- make modules
- make modules_install
- make install
- reboot
