[6d4c909]13 <para>The new instance of the shell that will start when the system is booted is a <emphasis>login</emphasis>

[2c6a9d5]25 <para>The <envar>LC_ALL</envar> variable controls the localization of
26 certain programs, making their messages follow the conventions of a
[24b004c]27 specified country.
[2c6a9d5]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
[e3a1e522]30 on your temporary system.</para>

[d1ff581]32 <para>By putting <filename class="directory">/tools/bin</filename> and
33 <filename class="directory">/tools/sbin</filename> at
[2c6a9d5]34 the end of the standard <envar>PATH</envar>, all the programs installed in
[134ba96]35 <xref linkend="chapter-temp-system"/> are only picked up by the shell
[2c6a9d5]36 if they have not yet been built on the target system. This configuration
[24b004c]37 forces use of the final system binaries as they are built over the
[e3a1e522]38 temp-system, minimising the chance of final system programs being built
[134ba96]39 against the temp-system.</para>
