   discusses the setup of an appropriate working environment. Please read
   <xref linkend="chapter-final-preps"/> carefully as it explains several
   important issues you need be aware of before beginning to
-  work your way through <xref linkend="chapter-temporary-tools"/> and beyond.</para>
+  work your way through <xref linkend="chapter-cross-tools"/> and beyond.</para>
 
-  <para><xref linkend="chapter-temporary-tools"/> explains the installation of
-  a number of packages that are needed to resolve circular
-  dependencies&mdash;for example, to compile a compiler, you need a compiler.
-  or to unpack the tar package, you need tar.</para>
+  <para><xref linkend="chapter-cross-tools"/>,  explains the installation of
+  the initial tool chain, (binutils, gcc, and glibc) using cross compilation
+  techniques to isolate the new tools from the host system.</para>
 
-  <para><xref linkend="chapter-temporary-tools"/> also shows you how to
-  build a C cross-compiling toolchain as a first step, including binutils
-  and GCC. Cross-compiling is not absolutely needed since the machine we'll
-  run LFS on is the same as the one we build on, but it has the advantage
-  of clearly separating the already installed system and the future LFS one.
-  The next step is to build Glibc, the C library. Glibc will be compiled by
-  the toolchain programs built previously. Then, the missing bits for a
-  C++ cross-compiling toolchain will be built. It is then possible to build
-  packages that are needed to resolve circular dependencies in such a way
-  that the produced executables and libraries are completely independent
-  from the installed distribution.</para>
+  <para><xref linkend="chapter-temporary-tools"/> shows you how to
+  cross-compile basic utilities using the just built cross-toolchain.</para>
 
-  <para>The remainder of <xref linkend="chapter-temporary-tools"/> adds
-  the packages necessary to get a complete build environment. This is done
-  after running the <command>chroot</command> (change root) program to enter
-  a virtual environment and start a new shell whose root directory will be
-  set to the LFS partition. This is very similar to rebooting and instructing
-  the kernel to mount the LFS partition as the root partition. The system
-  does not actually reboot, but instead uses <command>chroot</command>
-  because creating a bootable system requires additional work which is not 
-  ecessary just yet. The major advantage is that <quote>chrooting</quote>
-  allows to isolate the build process from the installed distribution, while
-  using the installed kernel.</para>
+  <para><xref linkend="chapter-chroot-temporary-tools"/> then enters a
+  "chroot" environment and uses the previously built tools to build
+  the additional tools needed to build and test the final system.</para>
 
   <para>This effort to isolate the new system from the host distribution may
   seem excessive. A full technical explanation as to why this is done is
