+  <title>Creating Directories</title>
+
+  <para>It is time to create the full structure in the LFS file system. Create
+  a standard directory tree by issuing the following commands:</para>
+
+<screen><userinput>mkdir -pv /{bin,boot,etc/{opt,sysconfig},home,lib/firmware,mnt,opt}
+mkdir -pv /{media/{floppy,cdrom},srv,var}
+install -dv -m 0750 /root
+install -dv -m 1777 /tmp /var/tmp
+mkdir -pv /usr/{,local/}{bin,include,lib,sbin,src}
+mkdir -pv /usr/{,local/}share/{color,dict,doc,info,locale,man}
+mkdir -pv  /usr/{,local/}share/{misc,terminfo,zoneinfo}
+mkdir -pv /usr/{,local/}share/man/man{1..8}
+
+mkdir -v /var/{log,mail,spool}
+ln -sv /run /var/run
+ln -sv /run/lock /var/lock
+mkdir -pv /var/{opt,cache,lib/{color,misc,locate},local}</userinput></screen>
+
+  <para>Directories are, by default, created with permission mode 755, but
+  this is not desirable for all directories. In the commands above, two
+  changes are made&mdash;one to the home directory of user <systemitem
+  class="username">root</systemitem>, and another to the directories for
+  temporary files.</para>
+
+  <para>The first mode change ensures that not just anybody can enter
+  the <filename class="directory">/root</filename> directory&mdash;the
+  same as a normal user would do with his or her home directory. The
+  second mode change makes sure that any user can write to the
+  <filename class="directory">/tmp</filename> and <filename
+  class="directory">/var/tmp</filename> directories, but cannot remove
+  another user's files from them. The latter is prohibited by the so-called
+  <quote>sticky bit,</quote> the highest bit (1) in the 1777 bit mask.</para>
+
+  <sect2>
+    <title>FHS Compliance Note</title>
+
+    <para>The directory tree is based on the Filesystem Hierarchy Standard
+    (FHS) (available at <ulink
+    url="https://refspecs.linuxfoundation.org/fhs.shtml"/>).  The FHS also specifies
+    the optional existence of some directories such as <filename
+    class="directory">/usr/local/games</filename> and <filename
+    class="directory">/usr/share/games</filename>.  We create only the
+    directories that are needed. However, feel free to create these
+    directories.  </para>
