Creating directories
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 -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. I haven't checked the FHS if they suggest
default modes for certain directories, so I'll just change the modes for
a few directories that make sense to change. 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 you would do with
/home/username directories). The second change is a mode 1777 for the tmp
directories. This way every user can write stuff to the /tmp directory if
they need to. The sticky (1) bit makes sure users can't delete other
user's file which they normally can do because the directory is set in
such a way that every body (owner, group, world) can write to that directory.
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 you have
downloaded in chapter 3 to some subdirectory under $LFS/usr/src (you will
need to create this subdirectory yourself).
