Beaucoup de raisons peuvent vous pousser à vouloir lire ce livre. Une des questions que beaucoup de monde se pose est « pourquoi se fatiguer à construire à la main un système Linux de A à Z alors qu'il suffit de télécharger et installer une distribution existante ? »
One important reason for this project's existence is to help you learn how a Linux system works from the inside out. Building an LFS system helps demonstrate what makes Linux tick, and how things work together and depend on each other. One of the best things this learning experience can provide is the ability to customize a Linux system to suit your own unique needs.
Another key benefit of LFS is that it gives you control of the system without relying on someone else's Linux implementation. With LFS, you are in the driver's seat. You dictate every aspect of your system.
LFS allows you to create very compact Linux systems. With other distributions you are often forced to install a great many programs you neither use nor understand. These programs waste resources. You may argue that with today's hard drives and CPUs, wasted resources are no longer a consideration. Sometimes, however, you are still constrained by the system's size, if nothing else. Think about bootable CDs, USB sticks, and embedded systems. Those are areas where LFS can be beneficial.
Another 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 want. 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 adequately fixes the problem.
Le but de Linux From Scratch est de construire les fondations d'un système complet et utilisable. Si vous ne souhaitez pas construire votre propre système à partir de rien, vous pourriez cependant bénéficier des informations contenues dans ce livre.
There are too many good reasons to build your own LFS system to list them all here. In the end, education is by far the most important reason. As you continue your LFS experience, you will discover the power that information and knowledge can bring.
