Contrast this with dedicated file servers, such as NetWare,
which can only share files with client computers (such as Windows workstations) and never act as
a client.
A file system is usually a structure of files and directories that exists on a single device
(such as a hard disk partition or CD-ROM). A Linux file system refers to the entire directory
structure (which may include file systems from several disks or NFS resources), beginning from
root (/) on a single computer. A shared directory in NFS may represent all or part of a computer??™s file
system, which can be attached (from the shared directory down the directory tree) to another computer??™s
file system.

Getting NFS
While nearly every Linux system supports NFS client and server features, NFS is not always installed
by default. You??™ll need different packages for different Linux systems to install NFS. Here are some
examples:
Fedora and other Red Hat Linux systems??”You need to install the nfs-utils package to
use Fedora as an NFS server. There is also a graphical NFS Configuration tool that requires
you to install the system-config-nfs package.
