NFS's roles in FOG

NFS is used to transfer images to and from clients in FOG, and is used on both the client and server. The server's setting file controls what files & directories are exported, and their options. NFS allows writing to the /images/dev directory and allows reading from the /images directory. During imaging, the client mounts either /images/dev (for uploading or capturing an image) or /images (for downloading or deploying an image).

During upload/capture, NFS uploads images into a folder in /images/dev/<MAC Address Of Client> During download/deployment, NFS downloads images from /images/<Image Path>
