  <title>Introduction</title>

  <para>This chapter shows how to compile and install a minimal Linux
  system. This system will contain just enough tools to start
  constructing the final LFS system in <xref
  linkend="chapter-building-system"/> and allow a working environment
  with more user convenience than a minimum environment would.</para>

  <para>There are two steps in building this minimal system. The first
  step is to build a new and host-independent toolchain (compiler,
  assembler, linker, libraries, and a few useful utilities).  The second
  step uses this toolchain to build the other essential tools.</para>

  <para>The files compiled in this chapter will be installed under the
  <filename class="directory">$LFS/tools</filename> directory to keep
  them separate from the files installed in <xref
  linkend="chapter-building-system"/> and the host production directories.
  Since the packages compiled here are temporary, we do not want them to
  pollute the soon-to-be LFS system.</para>

  <para>Check one last time that the <envar>LFS</envar> environment
  variable is set up properly:</para>

<screen><userinput>echo $LFS</userinput></screen>

  <para>Make sure the output shows the path to the LFS partition's mount
  point, which is <filename class="directory">/mnt/lfs</filename>, using
  our example.</para>
