+  <para>The <envar>LC_ALL</envar> variable controls the localization of
+  certain programs, making their messages follow the conventions of a
+  specified country. If the host system uses a version of Glibc older
+  than 2.2.4, having <envar>LC_ALL</envar> set to something other than
+  <quote>POSIX</quote> or <quote>C</quote> (during this chapter) may cause
+  issues if you exit the chroot environment and wish to return later.
+  Setting <envar>LC_ALL</envar> to <quote>POSIX</quote> or <quote>C</quote>
+  (the two are equivalent) ensures that everything will work as expected

-  hashing, limits the risk that old programs from the host are being used
-  when they should not be used any longer.</para>
+  <para>By putting <filename class="directory">/tools/bin</filename> at
+  the end of the standard <envar>PATH</envar>, all the programs installed in
+  <xref linkend="chapter-temporary-tools"/> are only picked up by the shell
+  if they have not yet been built on the target system. This configuration
+  forces use of the final system binaries as they are built over the 
+  temporary-tools, minimising the chance final system programs being built
+  against the temporary-tools.</para>
