    117           <para>The sysroot feature enables the linker to find shared objects
    118           which are required by other shared objects explicitly included on the
    119           linker's command line. Without this, some packages may not build
    120           successfully on some hosts.</para>
     117          <para>This defines a default (non-existent) sysroot directory
     118          <filename class="directory">/tools/$LFS_TGT/sys-root</filename>.
     119          It is useful when looking for shared objects which are required by
     120          other shared objects explicitly included on the linker's command
     121          line. Those objects are searched into the directories listed in
     122          <filename>&lt;sysroot&gt;/etc/ld.so.conf</filename>, and failing
     123          that, into the linker search path, which is right. If this switch
     124          is not given, <filename>/etc/ld.so.conf</filename> on the host
     125          is used, that is, programs may be linked to libraries on
     126          the host, which we want to avoid.</para>
