Modifiaction done to standard rpi3_defconfig

###Important --> to modify the files copy the original in 
		 output/target/ to your overlay folder and
		 then modify it.

---Misc---
1. add curl lib 

---To get SSH---
0.  buildroot add openssh package

1   /etc/network/interface to a static ip 
    {
        auto eth0
        iface eth0 inet satic
            address <ip>
            gateway <host ip>
            netmask <same has host>
            
    }

2.  /etc/init.d/S40network  modif to wait 5s before starting ifup. 
                            This because rpi3 netcard is slow to 
                            get up and running. Just add "sleep 5" 
                            in the start procedure. to check reboot
                            and use "ifconfig -a" dont forget 
                            "chmod 744" on this file to make exec
                            
3.  /etc/ssh/sshd_config --> allow root login. optional allow empty
                             password
                             
---Activate nfs---
#Target
1.  Busybox --> mount add NFS support
2.  Buildroot --> add target packages --> libraries --> networking --> libtirpc
#Host
3. Install nfs server --> sudo apt install nfs-kernel-server maybe also nfs-common ?
4. Perform this commands on the folder you wish to share
	4.1 sudo chown nobody:nogroup <folder_path>
	4.2 sudo chmod 777 <folder_path>
5.Modify server access to clients 
	5.1 sudo nano /etc/exports
	5.2 add this line <folder_path> <client_ip/or range>(rw,sync,no_subtree_check)
		EX : <folder_path> 192.168.1.0/24(rw,sync,no_subtree_check) allow
		all ip from 0 to 24
6.export config to host system --> sudo exportfs -a
7.restart server --> sudo systemctl restart nfs-kernel-server
8.Firewall open to client --> not done cause local network

#Target 
10.Try --> mount -t nfs <host_ip>:<folder_path> <target_mount_path> -o nolock
	Ex. mount -t nfs 192.168.1.4:/home/mattia/rpi3/shared /usr/workspace -o nolock
11.Modify fstab --> mkdir -p <mount_point_path>
		     <host_ip>:<folder_path> <target_mount_path> nfs hard,intr,nolock 0 0
12.Try it --> mount -a
