      <para>Here a temporary cross-compiled kernel will be built. When
      configuring it, select the minimal amount of options required to
      boot the target machine and build the final system. I.e., no support
      for sound, printers, etc. will be needed.</para>

      <para>Also, try to avoid the use of modules if possible, and don't
      use the resulting kernel image for production systems.</para>
