Setup NFS
===========================
This section covers the installation of several development tools for debugging and demenstrate how to use it. 

Setup and configure NFS server 
------------------------------

To share rootfs over network you need to install NFS server and configure it:

.. code-block:: bash

  sudo apt -y install nfs-kernel-server

Then, create a shared folder and set the permissions: 

.. code-block:: bash

  sudo mkdir /path/to/share/folder
  sudo chmod 777 /path/to/share/folder

Add the following line to /etc/exports and restart nfs server service:

.. code-block:: bash

   /path/to/share/folder *(rw,sync,no_root_squash,no_subtree_check)

.. code-block:: bash

   sudo exportfs -a
   sudo systemctl restart nfs-kernel-server

Create Yocto Image  
------------------

To bootup your image using NFS, you can add kas config file that contain the following parameters:

.. code-block:: bash

  header:
    version: 17
  local_conf_header:
    meta-otto-bsp: |
      ROOTFS_BOOT_TYPE = ...
      NFS_SERVER_IP = ...
      NFS_ROOTFS_PATH = ...
      NEWORK_CONFIG_TYPE = ...
      NETWORK_IP = ...
      NETWORK_NETMASK = ...
