Linux, FreeBSD and NetBSD [citation needed] OverlayFS is a union mount filesystem implementation for Linux. It combines multiple different underlying mount points into one, resulting in a single directory structure that contains underlying files and sub-directories from all sources.
Commonly done by calculating and storing hash function digests of files to detect if two files with different names, edit dates, etc., have identical contents. Programs which do not support it, will behave as if the originally-named file/directory has been deleted and the newly named file/directory is new and transmit the "new" file again.
The idea behind tmpfs is similar in concept to a RAM disk, in that both provide a file system stored in volatile memory; however, the implementations are different. While tmpfs is implemented at the logical file system layer, a RAM disk is implemented at the physical file system layer. In other words, a RAM disk is a virtual block device with a ...
This makes it possible for multiple users on multiple machines to share files and storage resources. Distributed file systems differ in their performance, mutability of content, handling of concurrent writes, handling of permanent or temporary loss of nodes or storage, and their policy of storing content.
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, [1] allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC
Its counterpart umount instructs the operating system that the file system should be disassociated from its mount point, making it no longer accessible and may be removed from the computer. It is important to umount a device before removing it since changes to files may have only partially been written and are completed as part of the umount .
To implement a new file system, a handler program linked to the supplied libfuse library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with ...
Unionfs is a filesystem service for Linux, FreeBSD and NetBSD which implements a union mount for other file systems.It allows files and directories of separate file systems, known as branches, to be transparently overlaid, forming a single coherent file system.
