     115  <para>Many modern linux distributions have merged <filename
     116  class="directory">/bin</filename> and <filename
     117  class="directory">/usr/bin</filename>. When this is the case, the standard
     118  <envar>PATH</envar> variable needs just to be set to <filename
     119  class="directory">/usr/bin/</filename> for the <xref
     120  linkend="chapter-temporary-tools"/> environment. When this is not the
     121  case, the following line adds <filename class="directory">/bin</filename>
     122  to the path.</para>

     129  <para>If <filename class="directory">/bin</filename> is not a symbolic
     130  link, then it has to be added to the <envar>PATH</envar> variable.</para>

    113137  <para>By putting <filename class="directory">$LFS/tools/bin</filename> ahead of the
    114   standard <envar>PATH</envar>, all the programs installed in <xref
    115   linkend="chapter-temporary-tools"/> are picked up by the shell immediately after
    116   their installation. This, combined with turning off hashing, limits the risk
    117   that old programs are used from the host when the same programs are available in
    118   the Chapter 5 environment.</para>
     138  standard <envar>PATH</envar>, the cross-compiler installed at the beginning
     139  of <xref linkend="chapter-temporary-tools"/> is picked up by the shell
     140  immediately after its installation. This, combined with turning off hashing,
     141  limits the risk that the compiler from the host be used instead of the
     142  cross-compiler.</para>
