Network File System (NFS)

Setting the Host

1 - Install NFS Service on host typing:

$sudo apt-get install nfs-kernel-server 

2 - Create symbolic link to ltib/rootfs

$sudo ln -s <ltib instalation folder>/rootfs /tftpboot/rootfs 

3 - Setup exports typing:

$sudo gedit /etc/exports 

and add the following line:

/tftpboot/rootfs/ *(rw,no_root_squash,no_subtree_check,async) 

4 - Restart the NFS server:

$sudo /etc/init.d/nfs-kernel-server restart 

Now the host is ready to use NFS.


Setting Target Linux Image to use NFS

1 - Run LTIB configuration typing:

$cd <ltib instalation folder> 
$./ltib -c

2 - On first page menu, go to "Target Image Generation -> Options" as in the picture below.


3 - Select the option NFS only and exit LTIB configuration to compile with the new configuration.


4 - LTIB should start new compiling and create a new Linux image on /<ltib instalation folder>/rootfs/boot/zImage

5 - Copy the created image on /<ltib instalation folder>/rootfs/boot/zImage to /tftpboot/zImage

6 - The system is ready to run with NFS. The root file system on target will be located on host on /<ltib instalation folder>/rootfs/
