| 13 |   <para>This chapter shows how to compile and install a minimal Linux
 | 
|---|
| 14 |   system. This system will contain just enough tools to start
 | 
|---|
| 15 |   constructing the final LFS system in <xref
 | 
|---|
| 16 |   linkend="chapter-building-system"/> and allow a working environment
 | 
|---|
| 17 |   with more user convenience than a minimum environment would.</para>
 | 
|---|
| 18 | 
 | 
|---|
| 19 |   <para>There are two steps in building this minimal system. The first
 | 
|---|
| 20 |   step is to build a new and host-independent toolchain (compiler,
 | 
|---|
| 21 |   assembler, linker, libraries, and a few useful utilities).  The second
 | 
|---|
| 22 |   step uses this toolchain to build the other essential tools.</para>
 | 
|---|
| 23 | 
 | 
|---|
| 24 |   <para>The files compiled in this chapter will be installed under the
 | 
|---|
| 25 |   <filename class="directory">$LFS/tools</filename> directory to keep
 | 
|---|
| 26 |   them separate from the files installed in <xref
 | 
|---|
| 27 |   linkend="chapter-building-system"/> and the host production directories.
 | 
|---|
| 28 |   Since the packages compiled here are temporary, we do not want them to
 | 
|---|
| 29 |   pollute the soon-to-be LFS system.</para>
 | 
|---|
| 30 | 
 | 
|---|
| 31 |   <para>Check one last time that the <envar>LFS</envar> environment
 | 
|---|
| 32 |   variable is set up properly:</para>
 | 
|---|
| 33 | 
 | 
|---|
| 34 | <screen><userinput>echo $LFS</userinput></screen>
 | 
|---|
| 35 | 
 | 
|---|
| 36 |   <para>Make sure the output shows the path to the LFS partition's mount
 | 
|---|
| 37 |   point, which is <filename class="directory">/mnt/lfs</filename>, using
 | 
|---|
| 38 |   our example.</para>
