[cbfa0a3]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
[3c2fa25]15 <filename>.bash_profile</filename> file now:</para>

[3c2fa25]25 <para>The <envar>LC_ALL</envar> variable controls the localization of
26 certain programs, making their messages follow the conventions of a
[351f7ef0]27 specified country.
[3c2fa25]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
[0636f6c]30 on your temporary system.</para>

[3c2fa25]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
[5be6331]34 <xref linkend="chapter-temp-system"/> are only picked up by the shell
[3c2fa25]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
[0636f6c]37 temp-system, minimising the chance of final system programs being built
[5be6331]38 against the temp-system.</para>
