rd16f745 r22a2710c 2 2 <title>Who would want to read this book</title> 3 3 4 <para>This book is intended for Linux users who want to setup their own 5 custom built Linux system. Reasons for wanting to build such a system are 6 diverse. Perhaps you want to get into more detail as to what 7 happens behind the scenes. Perhaps you are fed up with distributions 8 which are often bloated or perhaps you don't want to rely on pre-compiled 9 binaries due to security concerns. There are many other reasons why 10 someone may want a custom built system. If any of these reasons apply to 11 you, this book is meant for you.</para> 4 <para> 5 There are a lot of reasons why somebody would want to read this book in 6 order to install an LFS system. The question most people raise is "why 7 go through all the hassle of manually installing a Linux system from 8 scratch when you can just download an existing version like Debian or 9 Redhat". That is a valid question which I hope to answer for you. 10 </para> 12 11 13 <para>The fruits of building your own system are plentiful, but the labor may 14 be hard. There is a long way ahead, but in the end you will be 15 able to call yourself the proud owner of your own Linux system, 16 completely tailored after your needs. You will dictate the layout of 17 bootscripts, the file system hierarchy, which programs are installed in 18 which directory, which versions of software to use, and more. Perhaps the 19 most important reason is that you will know exactly what is installed where, 20 why, and how.</para> 12 <para> 13 The most important reason for LFS's existence is teaching people how a 14 Linux system works internally. Building an LFS system teaches you about 15 all that makes Linux tick, how things work together, and depend on each 16 other. And most importantly, how to customize it to your own taste and 17 needs. 18 </para> 19 20 <para> 21 One of the key benefits of LFS is that you are in control over your 22 system without having to rely on somebody else's Linux implementation 23 like Debian. You are in the driver's seat now and are able to dictate 24 every single thing such as the directory layout and boot script setup. 25 You will also know exactly where, why and how programs are installed. 26 </para> 27 28 <para> 29 Another benefit of LFS is that you can create a very compact Linux 30 system. When you install a distribution like Debian or RedHat, you end 31 up installing a lot of programs you would never in your life use. 32 They're just sitting there taking up (precious) disk space. It's not 33 hard to get an LFS system installed under 100 MB. Does that still sound 34 like a lot? A few of us have been working on creating a very small 35 embedded LFS system. We installed a system that was just enough to run 36 the Apache web server; total disk space usage was aproximately 8 MB. 37 With further stripping, that can be brought down to 5 MB or less. Try 38 that with a generic Debian or Redhat distribution. 39 </para> 40 41 <para> 42 If we were to compare a Linux distribution with a hamburger you buy at a 43 supermarket or fast-food restaurant, you would end up eating it without 44 knowing precisely what it is you are eating, whereas LFS gives you the 45 ingredients to make a hamburger. This allows you to carefully inspect 46 it, remove unwanted ingredients, and at the same time allow you to add 47 ingredients to enhance the flavour of your hamburger. When you are 48 satisfied with the ingredients, you go on to the next part of putting it 49 together. You now have the chance to make it just the way you like it: 50 broil it, bake it, deep-fry it, barbeque it, or eat it raw. 51 </para> 52 53 <para> 54 Another analogy that we can use is that of comparing LFS with a finished 55 house. LFS will give you the skeleton of a house, but it's up to you to 56 install plumbing, electrical outlets, kitchen, bathtub, wallpaper, etc. 57 </para> 58 59 <para> 60 Another advantage of a custom built Linux system is added security. You 61 will compile the entire system from source, thus allowing you to audit 62 everything, if you wish to do so, and apply all the security patches you 63 want or need to apply. You don't have to wait for somebody else to 64 provide a new binary package that fixes a security hole. Besides, you 65 have no guarantee that the new package actually fixes the problem 66 (adequately). You never truly know whether a security hole is fixed or 67 not unless you do it yourself. 68 </para> 21 69 22 70 </sect1>
