==== How to configure a NFS Server ====
One of the most important components of a Linux system is the root file system. A good development root file system provides the developer with all the useful tools that can help him/her on his/her work. Such a root file system can become very big in size, so it's hard to store it in flash memory. So the most convenient thing is to mount the whole root file system from the network, allowing the host system and the target to share the same files. In such a way, you can quickly modify the root file system, even “on the fly” (meaning that the file system can be modified while the system is running).
The most common way to setup a system like the one described is through NFS. As for tftp, installation and configuration depends on the Linux distribution on the host.

* For '''Debian/Ubuntu 8.x''':
** download the nfs packages with the preferred method. For example, run sudo apt-get install nfs-kernel-server nfs-common portmap
** when configuring portmap, do not bind loopback. If loopback is bound, reconfigure portmap (sudo dpkg-reconfigure portmap), then restart it: sudo /etc/init.d/portmap restart
** NFS exports from a server are controlled by the file /etc/exports. So, to export the directory /home/user, edit the /etc/exports file adding the following line. This line exports the "/home/user" directory with read and write permissions to all hosts.<br><pre>/home/user *(rw,sync,no_root_squash)</pre><br>
** Save the file and restart the server: sudo /etc/init.d/nfs-kernel-server restart


For other distributions, the procedure will be very similar: the NFS configuration is always modified editing the /etc/exports file. The packages names, the method to install them and how to restart the servers may vary.
