<title>How things are going to be done</title>

<para>
We are going to build the LFS system by using an already installed Linux
distribution such as Debian, SuSe, Slackware, Mandrake, RedHat, etc. There
is no need to have any kind of bootdisk. We will use an existing Linux
system as the base (since we need a compiler, linker, text editor, and
other tools).
</para>

<para>
After you have downloaded the necessary packages that make up an LFS
system you will create a new Linux native partition where the LFS system
will be installed onto.
</para>

<para>
The next step, chapter 5, will be the installation of a number of
packages that are statically linked and installed on the LFS partition.
These packages form a basic development suite which will be used to
install the actual system.
</para>

<para>
Chapter 6 installs the actual base system. We use the chroot program to
start a new shell who's root directory will be set to the LFS
partition. This, in essence, is the same as rebooting and have the
kernel mount the LFS partition as the root partition. The reason that
we don't actually reboot, but instead chroot, is that this way you can
still use your host system. While software is being installed you can
simply switch to a different VC (Virtual Console) or X desktop and
continue using your computer.
</para>

<para>
When all the software is installed, chapter 7 will setup the boot
scripts. Chapter 8 will setup the Linux boot loader and you can finally
reboot your system into LFS. The last step, after rebooting, is
setting up the networking tools and boot scripts. When you finish that
last step you will have finished the book and your LFS system is ready
for use.

<para>
This is the process in a nutshell. Detailed information on the steps
you are taking are provided in the chapters as you go through them. If
something isn't completely clear yet, don't worry. It will become very
clear shortly.
</para>

<para>
Please read chapter 2 carefully as it explains a few important things
you need to be aware of before you work your way through chapters 5 and
above.
