  <title>Creating a limited directory layout in LFS filesystem</title>

  <para>The first task performed in the LFS partition is to create a limited
  directory hierarchy so that programs compiled in <xref
  linkend="chapter-temporary-tools"/> (as well as glibc and libstdc++ in <xref
  linkend="chapter-cross-tools"/>) may be installed in their final
  location. This is needed so that those temporary programs be overwritten
  when rebuilding them in <xref linkend="chapter-building-system"/>.</para>

  <para>Create the required directory layout by running the following as
  <systemitem class="username">root</systemitem>:</para>

<screen><userinput>mkdir -pv $LFS/{bin,etc,lib,sbin,usr,var}
case $(uname -m) in
  x86_64) mkdir -pv $LFS/lib64 ;;
esac</userinput></screen>

  <para>Programs in <xref linkend="chapter-temporary-tools"/> will be compiled
  with a cross-compiler (more details in section <xref
  linkend="ch-tools-toolchaintechnotes"/>). In order to separate this
  cross-compiler from the other programs, it will be installed in a special
  directory. Create this directory with:</para>

<screen><userinput>mkdir -pv $LFS/tools</userinput></screen>
