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
15 <filename>.bash_profile</filename> file now:</para>

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 temporary 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 of final system programs being built
37 against the temp-system.</para>
