The world is no different operating systems. He has a part of the He-Man, Phantom, Arnold Schwarzenegger and George Bush. And ofcourse also have Linux, The Superman in the OS world.
Linux is stable, safe, fast and ...... it's free. S what do we get more code as well. Interestingly many articles about the benefits of Linux a more objective point - the code is free. Wrist and will remain only see the rules or forever. Linux is a lot of articles about how the revolution is the GNU and the other where a better distribution.
This article focuses only on one point to make their own Linux distribution. Until a few years ago most of us ordinary people to do a Linux distribution is a dream but then thank Gerard Beekmans, project leader and project start Linux From Scratch (LFS), this dream made easy. The first to ask one question would be - why do I want to LFS system?
If taken in the LFS site Gerard Beekmans own words --
There are many reasons why someone would want to install a LFS system. The question many people find what to go for all the complexity of manually install the Linux system if you can scratch just download the distro?. That is the question that I hope to answer lawful for you.
Important reason for LFS's existence is teaching people how the system works on Linux. Development of LFS system teaches you about all that makes Linux the answer, how all things work together, and depend on each other. And more importantly, how to Customize your own tastes and needs.
One of the main benefits of LFS is that you have control over your system without relying on other people Linux implementation. You are in the driver's seat now and everything to uphold such as layout and Boot setup script directory. You need to know exactly where, why and how these programs installed.
LFS is another advantage that you can build a Linux system is very compact. When you install this distribution, you could end up closing a lot of programs you may never use. They sat there taking (precious) disk space. It is not difficult to obtain LFS system installed under 100 MB. Does that still sound like a lot? Some of us who have worked to build a very small embedded LFS system. We set up a system sufficient to run the Apache web server; total disk space to use approximately 8 MB. Stripping and many more, which can be brought down to 5 MB or less. Try that with a normal distribution.
If we compare the distribution of Linux and Burger did not buy at the supermarket or fast food restaurants, you're eating the actual end without knowing what you eat, where they do not give you material Burger LFS. This allows you to check carefully, remove materials that are not desirable, while allowing you to add links and multiply your taste is not Burger. When you are satisfied with the link, you can go to the second part is put together. You now have the opportunity to do is exactly as you like: bake it, bake it, deep-fry it, Barbecue, or eaten raw.
Another comparison that we can use is to compare the LFS and finish the house. LFS will provide a framework houses, but you have to install pipes, electrical outlets, kitchen, bathtub, wallpaper, etc.
Another advantage of Linux system specially built additional security. You will need to collect from the source system, allowing you to audit everything, if you want to do it, and implement security Matches all you want or need to pray. Q You do not wait for someone else to provide a new binary package that repairs a security hole. In addition, you have no guarantee that the new package repair problems (enough). Really can not know whether the security hole is fixed or to save themselves.
One of the reasons why the ACS to do better than Intels is that this program created specifically for the equipment of all people benefit from the equipment. However, more than any Intel i386-based systems and written in because the speed of the newer processor is one of seeing a better performance but never peak performance that is not capable of modern processors. LFS change any aspect of the scale. LFS is generally on target Ordered systems. This means that programs can be Produced primarily for equipment, resulting in maximum performance. I even exposed my LFS uses processing speed and the maximum amount of RAM I could buy. But now I'm happy and PIII 800. I also run the latest kernel and KDE Apps is that many serious people who can think and I still feel good about the computer. And in this case Speed thrills and still not be killed. Killing or maybe another distro. ;-)
Now that we are all convinced that the LFS is the way to go, we II talked about how to go about the implementation of the LFS. Making our own distro we want you must first have a good system where Linux. For that we can each system that can collect Linux code and the GNU system GNU C + + compiler should do the trick. This is called the host system. Host system can taste like Red Hat Linux, Fedora, Debian, Slackware, etc. as a Unix or FreeBSD, NetBSD etc.. Host system to the compiler, linker and the shell building new systems. Host system must also be able to read and write to the file system recognized by the Linux kernel as ext3, ReiserFS, XFS, etc.
After the system a good host for the necessary development environment installed, the next step is to build a linux native guards will calculate Ordered LFS. This requires calculating and formatted file system required. A number of packages installed, then the basic form or shape Suite development toolchain. Toolchain is a system that is then used to build a real distro. Toolchain built in two phases - the first host-independent toolchain built statically by the compiler is installed, assember, linker, libraries and other essential services. Another important tool and then built on this first stage of the system.
Root (change root) program is then used to enter the virtual environment and start a new shell root directory which will be established to calculate the LFS. The packages then LFS Arranged in this environment after chroot Booting the installed scripts. Finally, the kernel and boot loader installed and reboot the machine with all new custom distributions.
This process may seem a bit difficult but fun along the way and the results are truly beautiful.
I have taken a workshop in early 2004 at our office on the subject. I quoted the mine as the team's view that attending the workshop.
