This chapter, along with the previous one, covered in a lot of detail how to build the Linux kernel from source. We began with the actual kernel (and kernel modules') build process. Once built, we showed how the kernel modules are to be installed onto the system. We then moved on to both the practicalities of generating the initramfs (or initrd) image and went on to explain the motivation behind it. The final step in the kernel build was the (simple) customization of the bootloader (here, we focused only on x86 GRUB). We then showed how to boot the system via the newly baked kernel and verify that its configuration is as we expect. As a useful add-on, we then showed (the basics) of how we can even cross-compile the Linux kernel for another processor (ARM, in this instance). Finally, we shared some additional tips to help you with the kernel build.
Again, if you haven't done so already, we urge you to carefully review and try out the procedures mentioned here and build...
