To create a development structure for EOS, you must create a directory in the place you want. In the following example we'll use the directory "/roo/EOS".

Example:

[root@linux ~]# mkdir -p ~/EOS/

[root@linux ~]# cd EOS

Download the installer source (installer.tgz).

[root@linux ~]# wget http://eos.brc.com.br/installer.tgz

Download the EOS-Linux iso.

[root@linux~]# wget http://eos.brc.com.br/linux-eos-1.3.3.iso

Create a directory to enabling mount the file .iso and mount an iso 

[root@linux~]# mkdir mount

[root@linux~]# mount -o loop linux-eos-1.3.3.iso mount

Create the Directory that you'll use to develop, and copy for it the content of the mount directory.

[root@linux~]# mkdir CDFS

[root@linux~]# cp -a mount/* CDFS

Till this point you can already generate a new Linux EOS iso with the following command:

[root@linux~]# mkisofs -o eos-linux.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -allow-lowercase -allow-multidot -no-emul-boot -boot-load-size 4 -boot-info-table -J -R -v -l -T CDFS
