11 <title>Creating a limited directory layout in LFS filesystem</title>
12
13 <para>In this section, we begin populating the LFS filesystem with the
14 pieces that will constitute the final Linux system. The first step is to
15 create a limited directory hierarchy, so that the programs compiled in <xref
16 linkend="chapter-temporary-tools"/> (as well as glibc and libstdc++ in <xref
17 linkend="chapter-cross-tools"/>) can be installed in their final
18 location. We do this so those temporary programs will be overwritten when
19 the final versions are built in <xref linkend="chapter-building-system"/>.</para>
20
21 <para>Create the required directory layout by issuing the following commands as
22 <systemitem class="username">root</systemitem>:</para>
23
24<screen><userinput>mkdir -pv $LFS/{etc,var} $LFS/usr/{bin,lib,sbin}
25
26for i in bin lib sbin; do
27 ln -sv usr/$i $LFS/$i
28done
29
30case $(uname -m) in
31 x86_64) mkdir -pv $LFS/lib64 ;;
32esac</userinput></screen>
33
34 <para>Programs in <xref linkend="chapter-temporary-tools"/> will be compiled
35 with a cross-compiler (more details can be found in section <xref
36 linkend="ch-tools-toolchaintechnotes"/>). This cross-compiler will be installed
37 in a special directory, to separate it from the other programs. Still acting as
38 &root;, create that directory with this command:</para>
39
