   <title>Introduction</title>
 
-  <para>This chapter shows how to build 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>This chapter shows how to cross-compile basic utilities using
+  the just built cross-toolchain. Those utilities are installed into
+  their final location, but cannot be used yet. Basic tasks still rely on
+  the hosts tools. Nevertheless, the installed libraries are used when
+  linking.</para>
+
+  <para>Using the utilities will be possible in next chapter after entering
+  the <quote>chroot</quote> environment. But all the packages built in the
+  present chapter need themselves to be built. So we cannot be independent
+  on the build system yet.</para>
+
+  <para>Once again, let us recall that improper setting of <envar>LFS</envar>
+  together with building as root, may render your computer unusable.
+  This whole chapter must be done as user <systemitem
+  class="username">lfs</systemitem>, with the enviroment as described in
+  <xref linkend="ch-preps-settingenviron"/>.</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</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>
