    <para>There's an internal issue with Coreutils which makes some of the
    programs behave abnormally if you build using an older kernel. Apply a
    patch to fix the issue:</para>

<screen><userinput remap="pre">patch -Np1 -i ../&coreutils-old-kernel-patch;</userinput></screen>

    <para>Prepare Coreutils for compilation:</para>

<screen><userinput remap="configure">./configure --prefix=/tools --enable-install-program=hostname</userinput></screen>

      <title>The meaning of the configure options:</title>

        <listitem>
          <para>This enables the <command>hostname</command> binary to be built
          and installed &ndash; it is disabled by default but is required by the
          Perl test suite.</para>
        </listitem>
      </varlistentry>

    <para>Compile the package:</para>

<screen><userinput remap="make">make</userinput></screen>

    <para>To test the results, issue:</para>

<screen><userinput remap="test">make RUN_EXPENSIVE_TESTS=yes check</userinput></screen>

    <para>The <parameter>RUN_EXPENSIVE_TESTS=yes</parameter> parameter tells the
    test suite to run several additional tests that are considered
    relatively expensive (in terms of CPU power and memory usage) on some
    platforms, but generally are not a problem on Linux.</para>

    <para>Install the package:</para>

<screen><userinput remap="install">make install</userinput></screen>

    <para>The above command refuses to install <filename>su</filename>
    because it cannot install it setuid root as a non-privileged user. By
    manually installing it with a different name, we can use it for running
    tests in the final system as a non-privileged user and we keep a possibly
    useful <command>su</command> from our host first place in our PATH. Install
    it with:</para>

<screen><userinput remap="install">cp -v src/su /tools/bin/su-tools</userinput></screen>
