The /etc/fstab file describes how mount(8) should assemble a system's file name hierarchy from various independent file systems (including file systems exported by NFS servers).
Each line in the /etc/fstab file describes a single file system, its mount point, and a set of default mount options for that mount point.
For example: The server's hostname and export pathname are separated by a colon, while the mount options are separated by commas.The remaining fields are separated by blanks or tabs.The server's hostname can be an unqualified hostname, a fully qualified domain name, a dotted quad IPv4 address, or an IPv6 address enclosed in square brackets.Link-local and site-local IPv6 addresses must be accompanied by an interface identifier.See ipv6(7) for details on specifying raw IPv6 addresses. Use of the "nfs4" fstype in /etc/fstab is deprecated.
Refer to mount(8) for a description of generic mount options available for all file systems.
If you do not need to specify any mount options, use the generic option defaults in /etc/fstab.
NFS is an Internet Standard protocol created by Sun Microsystems in 1984.
NFS was developed to allow file sharing between systems residing on a local area network.
The Linux NFS client supports three versions of the NFS protocol: NFS version 2 [RFC1094], NFS version 3 [RFC1813], and NFS version 4 [RFC3530].
The mount(8) command attaches a file system to the system's name space hierarchy at a given mount point.
