-<title>Who would want to read this book</title>
|
|
|
-
|
|
|
-<para>There are many reasons why somebody would want to read this book. The
|
|
|
-principal reason being to install a Linux system straight from the source
|
|
|
-code. A question many people raise is <quote>Why go through all the hassle of
|
|
|
-manually building a Linux system from scratch when you can just download and
|
|
|
-install an existing one?</quote>. That is a good question and is the impetus for
|
|
|
-this section of the book.</para>
|
|
|
-
|
|
|
-<para>One important reason for LFS's existence is to help people learn how a
|
|
|
-Linux system works from the inside out. Building an LFS system helps demonstrate
|
|
|
-to you what makes Linux tick, how things work together and depend on each
|
|
|
-other. One of the best things that this learning experience provides is the
|
|
|
-ability to customize Linux to your own tastes and needs.</para>
|
|
|
-
|
|
|
-<para>A key benefit of LFS is that you have more control of your system
|
|
|
-without relying on someone else's Linux implementation. With LFS, you are
|
|
|
-in the driver's seat and dictate every aspect of your system, such as the
|
|
|
-directory layout and bootscript setup. You also dictate where, why and how
|
|
|
-programs are installed.</para>
|
|
|
-
|
|
|
-<para>Another benefit of LFS is the ability to create a very compact Linux
|
|
|
-system. When installing a regular distribution, you are usually forced to
|
|
|
-install several programs which you are likely never to use. They're just
|
|
|
-sitting there wasting precious disk space (or worse, CPU cycles). It isn't
|
|
|
-difficult to build an LFS system of less than 100 MB. Does that still sound like a
|
|
|
-lot? A few of us have been working on creating a very small embedded LFS
|
|
|
-system. We successfully built a system that was just enough to run the Apache
|
|
|
-web server with approximately 8MB of disk space used. Further stripping could
|
|
|
-bring that down to 5 MB or less. Try that with a regular distribution.</para>
|
|
|
-
|
|
|
-<para>We could compare Linux distributions to a hamburger you buy at a
|
|
|
-fast-food restaurant - you have no idea what you are eating. LFS, on the
|
|
|
-other hand, doesn't give you a hamburger, but the recipe to make a hamburger.
|
|
|
-This allows you to review it, to omit unwanted ingredients, and to
|
|
|
-add your own ingredients which enhance the flavor of your burger. When you
|
|
|
-are satisfied with the recipe, you go on to preparing it. You make it just
|
|
|
-the way you like it: broil it, bake it, deep-fry it, barbecue it, or eat it
|
|
|
-tar-tar (raw).</para>
|
|
|
-
|
|
|
-<para>Another analogy that we can use is that of comparing LFS with a
|
|
|
-finished house. LFS will give you the skeletal plan of a house, but it's up
|
|
|
-to you to build it. You have the freedom to adjust your plans as you
|
|
|
-go.</para>
|
|
|
-
|
|
|
-<para>One last advantage of a custom built Linux system is security.
|
|
|
-By compiling the entire system from source code, you are empowered to audit
|
|
|
-everything and apply all the security patches you feel are needed. You don't
|
|
|
-have to wait for somebody else to compile binary packages that fix a security
|
|
|
-hole. Unless you examine the patch and implement it yourself you have no
|
|
|
-guarantee that the new binary package was built correctly and actually fixes the
|
|
|
-problem (adequately).</para>
|
|
|
-
|
|
|
-<para>There are too many good reasons to build your own LFS system for them all
|
|
|
-to be listed here. This section is only the tip of the iceberg. As you
|
|
|
-continue in your LFS experience, you will find on your own the power that
|
|
|
-information and knowledge truly bring.</para>

-<title>Who would not want to read this book</title>
|
|
|
-
|
|
|
-<para>There are probably some who, for whatever reason, would feel that they do not
|
|
|
-want to read this book. If you do not wish to build your own Linux system from
|
|
|
-scratch, then you probably don't want to read this book. Our goal is to help
|
|
|
-you build a complete and usable foundation-level system. If you only want to
|
|
|
-know what happens while your computer boots, then we recommend the <quote>From
|
|
|
-Power Up To Bash Prompt</quote> HOWTO. The HOWTO builds a bare system which is
|
|
|
-similar to that of this book, but it focuses strictly on creating a system
|
|
|
-capable of booting to a BASH prompt.</para>
|
|
|
-
|
|
|
-<para>While you decide which to read, consider your objective. If you wish
|
|
|
-to build a Linux system while learning a bit along the way, then this book
|
|
|
-is probably your best choice. If your objective is strictly educational and
|
|
|
-you do not have any plans for your finished system, then the
|
|
|
-<quote>From Power Up To Bash Prompt</quote> HOWTO is probably a better choice.</para>
