If you are reading this, I assume you already know what the
Linux kernel is and why you may want to update it. However, if you are accidentally reading this walkthrough, just happen to be running Linux, and have no idea what the kernel is or why you would want to update it, the next two paragraphs are for you (if you are looking instead into a less verbose and more generic way of updating your kernel on any Linux distro,
read here). In a neophyte nutshell, the Linux kernel is the brain of the Linux system. It tells your system which file systems, hardware, protocols, etc. are supported. There is a lot more to it than that, of course, but I think that diminutive description will suffice for now.
Hey guys, we can sit here and debate why the author chose to highlight the subject the way he did and call each other names, but why not just wait until tomorrow and ask him directly? I work with the author and would have asked him directly for you all, but he wasn't at work today.
I don't know his reasoning, but there are a thousand different ways to obtain, configure and compile a kernel. Perhaps he just didn't want to write a book here. Who knows? We all will tomorrow if we ask him. Can we all agree not to kill each other until then?
