[ba82c18]11 <title>Creating a limited directory layout in LFS filesystem</title>
[2ed0e93]13 <para>The next task to be performed in the LFS partition is to create a limited
14 directory hierarchy, so that the programs compiled in <xref
[430a8de]15 linkend="chapter-temporary-tools"/> (as well as glibc and libstdc++ in <xref
[2ed0e93]16 linkend="chapter-cross-tools"/>) can be installed in their final
17 location. We do this so those temporary programs will be overwritten when
18 the final versions are built in <xref linkend="chapter-building-system"/>.</para>
[2ed0e93]20 <para>Create the required directory layout by issuing the following commands as
[efcb393]21 <systemitem class="username">root</systemitem>:</para>
[96dda27a]23<screen><userinput>mkdir -pv $LFS/{boot,etc,var} $LFS/usr/{bin,lib,sbin}
25for i in bin lib sbin; do
26 ln -sv usr/$i $LFS/$i
[96dda27a]29 <para>Some targets (for example, x86_64) needs
30 <filename class="directory">/lib64</filename> directory. If you are
31 building for one of those targets, create it as
32 <systemitem class="username">root</systemitem>:</para>
34<screen><userinput>mkdir -pv $LFS/lib64</userinput></screen>
36 <para>Programs in <xref linkend="chapter-temporary-tools"/> will be compiled
[2ed0e93]37 with a cross-compiler (more details can be found in section <xref
38 linkend="ch-tools-toolchaintechnotes"/>). This cross-compiler will be installed
39 in a special directory, to separate it from the other programs. Still acting as
40 &root;, create that directory with this command:</para>
42<screen><userinput>mkdir -pv $LFS/tools</userinput></screen>
