Let's create the directory tree on the LFS partition according to the FHS standard which can be found at http://www.pathname.com/fhs/. Issuing the following commands will create the necessary directories:
cd $LFS
mkdir bin boot dev etc home lib mnt proc root sbin tmp usr var
cd $LFS/usr
mkdir bin include lib sbin share src
ln -s share/man man
ln -s share/doc doc
ln -s share/info info
ln -s . local
ln -s ../etc etc
ln -s ../var var
cd $LFS/usr/share
mkdir dict doc info locale man nls misc terminfo zoneinfo
cd $LFS/usr/share/man
mkdir man1 man2 man3 man4 man5 man6 man7 man8
cd $LFS/var
mkdir lock log run spool tmp
Now that the directories are created, copy the source files you have downloaded in chapter 3 to some subdirectory under $LFS/usr/src (you will need to create this subdirectory yourself).
