13  <para>The new instance of the shell that will start when the system is booted is a <emphasis>login</emphasis>
14  shell, which will read <filename>.bash_profile</filename> file. Create the

25  <para>The <envar>LC_ALL</envar> variable controls the localization of
26  certain programs, making their messages follow the conventions of a
27  specified country.
28  Setting <envar>LC_ALL</envar> to <quote>POSIX</quote> or <quote>C</quote>
29  (the two are equivalent) ensures that everything will work as expected
30  on your temporary system.</para>
31
32  <para>By putting <filename class="directory">/tools/bin</filename> at
33  the end of the standard <envar>PATH</envar>, all the programs installed in
34  <xref linkend="chapter-temp-system"/> are only picked up by the shell
35  if they have not yet been built on the target system. This configuration
36  forces use of the final system binaries as they are built over the
37  temp-system, minimising the chance of final system programs being built
38  against the temp-system.</para>
