The typical developing environment for an Embedded Linux system is composed of a host machine and a target machine. The host is used by the developer to compile the code that will run on the target. In our case the target is obviously the Diva module, while the host is assumed to be a PC running the Linux operating system. The Linux kernel running on the target can mount the root file system from different physical media. During the software development, we strongly recommend using a directory exported via NFS by the host for this purpose (see the example configuration called [[Prodotti_-_Dave_-_Diva_(DDx)_-_doc_-_Software_ManualBooting_Linux_Kernel#Net_nfs Configuration_net_nfs | net_nfs]]).
