24  <para>The <envar>LC_ALL</envar> variable controls the localization of
25  certain programs, making their messages follow the conventions of a
26  specified country.
27  Setting <envar>LC_ALL</envar> to <quote>POSIX</quote> or <quote>C</quote>
28  (the two are equivalent) ensures that everything will work as expected
29  on your tempoary system.</para>

31  <para>By putting <filename class="directory">/tools/bin</filename> at
32  the end of the standard <envar>PATH</envar>, all the programs installed in
33  <xref linkend="chapter-temp-system"/> are only picked up by the shell
34  if they have not yet been built on the target system. This configuration
35  forces use of the final system binaries as they are built over the
36  temp-system, minimising the chance final system programs being built
37  against the temp-system.</para>
