Creating directories
Let's create the directory tree on the LFS partition based on the FHS
standard, which can be found at http://www.pathname.com/fhs/.
Issuing the following commands will create a default directory layout:
cd $LFS
mkdir -p bin boot dev/pts etc home lib mnt proc root sbin
tmp var
for dirname in $LFS/usr $LFS/usr/local
do
mkdir $dirname
cd $dirname
mkdir bin etc include lib sbin share
src tmp var
ln -s share/man man
ln -s share/doc doc
ln -s share/info info
cd $dirname/share
mkdir dict doc info locale man nls misc
terminfo zoneinfo
cd $dirname/share/man
mkdir man1 man2 man3 man4 man5 man6 man7
man8
done
cd $LFS/var
mkdir lock log mail run spool tmp
Normally, directories are created with permission mode 755, which isn't
desired for all directories. The first change is a mode 0750 for the
$LFS/root directory. This is to make sure that not just everybody can
enter the /root directory (the same a user would do with /home/username
directories). The second change is a mode 1777 for the tmp
directories. This way, any user can write data to the /tmp directory but
cannot remove another user's files (the latter is caused by
the so-called "sticky bit" - bit 1 of the 1777 bit mask).
cd $LFS &&
chmod 0750 root &&
chmod 1777 tmp usr/tmp usr/local/tmp var/tmp
Now that the directories are created, copy the source files that were
downloaded in chapter 3 to some subdirectory under $LFS/usr/src (you
will need to create the desired directory yourself).
