| 13 | <para>The Linux From Scratch Project has seen many changes in the
|
|---|
| 14 | few years of its existence. I personally became involved with the
|
|---|
| 15 | project in 1999, around the time of the 2.x releases. At that time,
|
|---|
| 16 | the build process was to create static binaries with the host system,
|
|---|
| 17 | then chroot and build the final binaries on top of the static ones.</para>
|
|---|
| 18 |
|
|---|
| 19 | <para>Later came the use of the /static directory to hold the initial
|
|---|
| 20 | static builds, keeping them separated from the final system, then
|
|---|
| 21 | the PureLFS process developed by Ryan Oliver and Greg Schafer,
|
|---|
| 22 | introducing a new toolchain build process that divorces even our initial
|
|---|
| 23 | builds from the host. Finally, LFS 6 bought Linux Kernel 2.6, the
|
|---|
| 24 | udev dynamic device structure, sanitized kernel headers, and other
|
|---|
| 25 | improvements to the Linux From Scratch system.</para>
|
|---|
| 26 |
|
|---|
| 27 | <para>The one "flaw" in LFS is that it has always been based on a x86
|
|---|
| 28 | class processor. With the advent of the Athlon 64 and Intel EM64T
|
|---|
| 29 | processors, the x86-only LFS is no longer ideal. Throughout this time,
|
|---|
| 30 | Ryan Oliver developed and documented a process by which you could
|
|---|
| 31 | build Linux for any system and from any system, by use of
|
|---|
| 32 | cross-compilation techniques. Thus, the Cross LFS project was born.</para>
|
|---|
| 33 |
|
|---|
| 34 | <para>CLFS follows the same guiding principles the LFS project has
|
|---|
| 35 | always followed, e.g., knowing your system inside and out by virtue
|
|---|
| 36 | of having built the system yourself. Additionally, during a CLFS
|
|---|
| 37 | build, you will learn advanced techniques such as cross-build toolchains,
|
|---|
| 38 | multilib support (32 & 64-bit libraries side-by-side), alternative
|
|---|
| 39 | architectures such as Sparc, MIPS, and Alpha, and much more.</para>
|
|---|
| 40 |
|
|---|
| 41 | <para>We hope you enjoy building your own CLFS system, and the benefits
|
|---|
| 42 | that come from a system tailored to your needs!</para>
