-<para>See testing.</para>
+<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 the next chapter 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>Before issuing the build instructions for a package, the package
+should be unpacked as user <emphasis>lfs</emphasis>, and a
+<command>cd</command> into the created directory should be performed. The build
+instructions assume that the <command>bash</command> shell is in use.</para>
+
+<para>Several of the packages are patched before compilation, but only
+when the patch is needed to circumvent a problem. A patch is often
+needed in both this and the next chapter, but sometimes in only one or
+the other. Therefore, do not be concerned if instructions for a downloaded
+patch seem to be missing. Warning messages about
+<emphasis>offset</emphasis> or <emphasis>fuzz</emphasis> may
+also be encountered when applying a patch. Do not worry about these
+warnings, as the patch was still successfully applied.</para>
+
+<para>During the compilation of most packages, there will be several
+warnings that scroll by on the screen. These are normal and can safely
+be ignored. These warnings are as they appear&mdash;warnings about
+deprecated, but not invalid, use of the C or C++ syntax. C standards
+change fairly often, and some packages still use the older standard.
+This is not a problem, but does prompt the warning.</para>
+
+<para>After installing each package, delete its source and build
+directories, unless specifically instructed otherwise. Deleting the
+sources saves space and prevents mis-configuration when the same
+package is reinstalled later. Only three of the packages need to
+retain the source and build directories in order for their contents to
+be used by later commands. Pay special attention to these
+reminders.</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>
