# 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).
