[cff800e] | 13 | <para>The LFS system will be built by using an already installed
|
---|
[448e226] | 14 | Linux distribution (such as Debian, OpenMandriva, Fedora, or openSUSE). This
|
---|
[13a9dc2] | 15 | existing Linux system (the host) will be used as a starting point to
|
---|
| 16 | provide necessary programs, including a compiler, linker, and shell,
|
---|
| 17 | to build the new system. Select the <quote>development</quote> option
|
---|
[99ecc76] | 18 | during the distribution installation to include these
|
---|
[13a9dc2] | 19 | tools.</para>
|

[81fd230] | 20 |
|
---|
[99ecc76] | 21 | <para>As an alternative to installing a separate distribution on your
|
---|
[9fb74db] | 22 | machine, you may wish to use <!-- the Linux From Scratch LiveCD or --> a LiveCD from a
|
---|
| 23 | commercial distribution. <!-- The LFS LiveCD works well as a host system,
|
---|
[a91be49] | 24 | providing all the tools you need to successfully follow the instructions in
|
---|
[e5fda02] | 25 | this book. The LiveCD version is behind the current book, but is still useful
|
---|
[7928e023] | 26 | as a host for building the current book. The <quote>-nosrc</quote> or
|
---|
| 27 | <quote>-min</quote> editions of the LiveCD are the most appropriate for
|
---|
| 28 | building a current LFS system. For more information about the LFS LiveCD or
|
---|
[9fb74db] | 29 | to download a copy, visit <ulink url="&livecd-root;"/>. --></para>

[13a9dc2] | 38 | <para><xref linkend="chapter-partitioning"/> of this book describes how
|
---|
[99ecc76] | 39 | to create a new Linux native partition and file system,
|
---|
[13a9dc2] | 40 | where the new LFS system will be compiled and installed. <xref
|

| 41 | linkend="chapter-getting-materials"/> explains which packages and
|
---|
[99ecc76] | 42 | patches must be downloaded to build an LFS system, and how to store
|
---|
[13a9dc2] | 43 | them on the new file system. <xref linkend="chapter-final-preps"/>
|
---|
[fdb65bd] | 44 | discusses the setup of an appropriate working environment. Please read
|
---|
[13a9dc2] | 45 | <xref linkend="chapter-final-preps"/> carefully as it explains several
|
---|
[99ecc76] | 46 | important issues you should be aware of before you begin to
|
---|
[3369724] | 47 | work your way through <xref linkend="chapter-cross-tools"/> and beyond.</para>
|
---|
[81fd230] | 48 |
|
---|
[1184a7e] | 49 | <para><xref linkend="chapter-cross-tools"/> explains the installation of
|
---|
[99ecc76] | 50 | the initial tool chain, (binutils, gcc, and glibc) using cross-compilation
|
---|
[3369724] | 51 | techniques to isolate the new tools from the host system.</para>
|
---|
[81fd230] | 52 |
|
---|
[3369724] | 53 | <para><xref linkend="chapter-temporary-tools"/> shows you how to

[3369724] | 56 | <para><xref linkend="chapter-chroot-temporary-tools"/> then enters a

---|
[0f9c02a] | 57 | "chroot" environment, where we use the new tools to build all
|
---|
[99ecc76] | 58 | the rest of the tools needed to create the LFS system.</para>
|
---|
[81fd230] | 59 |
|

[13a9dc2] | 60 | <para>This effort to isolate the new system from the host distribution may
|
---|
[efcb393] | 61 | seem excessive. A full technical explanation as to why this is done is

| 62 | provided in <xref linkend="ch-tools-toolchaintechnotes"/>.</para>

[81fd230] | 63 |
|
---|
[1184a7e] | 64 | <para>In <xref linkend="chapter-building-system"/> the
|
---|
[99ecc76] | 65 | full-blown LFS system is built. Another advantage provided by the chroot
|
---|
[3a56c9a] | 66 | environment is that it allows you to continue using the host system
|
---|
[efcb393] | 67 | while LFS is being built. While waiting for package compilations to
|
---|
[99ecc76] | 68 | complete, you can continue using your computer as usual.</para>

[87899e5] | 69 |
|
---|
[1118b17] | 70 | <para>To finish the installation, the basic system configuration is set up in
|
---|
[99ecc76] | 71 | <xref linkend="chapter-config"/>, and the kernel and boot loader are created
|
---|
| 72 | in <xref linkend="chapter-bootable"/>. <xref linkend="chapter-finalizing"/>
|
---|
[cff800e] | 73 | contains information on continuing the LFS experience beyond this book.
|
---|
[99ecc76] | 74 | After the steps in this chapter have been implemented, the computer is

| 75 | ready to boot into the new LFS system.</para>

[13a9dc2] | 76 |

[99ecc76] | 78 | step is presented in the following chapters.
