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.
The organization is called a filesystem. Each different filesystem provides the host operating system with metadata so that it knows how to read and write data. When the medium (or media, when the filesystem is a volume filesystem as in RAID arrays) is mounted, these metadata are read by the operating system so that it can use the storage. [2] [3]
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.
Development began in earnest in 2007, with the first stable release made to Linux kernel 2.6.27 in October 2008. [4] Two major differences between UBIFS and JFFS2 are that UBIFS supports write caching, [5] and UBIFS errs on the pessimistic side of free space calculation. [6] UBIFS tends to perform better than JFFS2 for large NAND flash memory ...
All of the Linux filesystem drivers support all three FAT types, namely FAT12, FAT16 and FAT32.Where they differ is in the provision of support for long filenames, beyond the 8.3 filename structure of the original FAT filesystem format, and in the provision of Unix file semantics that do not exist as standard in the FAT filesystem format such as file permissions. [1]
The mount command instructs the operating system that a file system is ready to use, and associates it with a particular point in the overall file system hierarchy (its mount point) and sets options relating to its access. Mounting makes file systems, files, directories, devices and special files available for use and available to the user.
Mounting a file containing a file system via such a loop mount makes the files within that file system accessible. They appear in the mount point directory. A loop device may allow some kind of data elaboration during this redirection. For example, the device may be the unencrypted version of an encrypted file.
It is also used in Chromecast, [2] in Tiny Core Linux for packaging extensions, and for the system partitions of some Android releases (Android Nougat). [3] It is often combined with a union mount filesystem, such as UnionFS, OverlayFS, or aufs, to provide a read-write environment for live Linux distributions. This takes advantage of both ...
