The name originally stood for AnotherUnionFS until version 2. Developed by Junjiro Okajima in 2006, [ 1 ] aufs is a complete rewrite of the earlier UnionFS . It aimed to improve reliability and performance, but also introduced some new concepts, like writable branch balancing, [ 2 ] and other improvements – some of which are now implemented ...
All the gnome-mount programs utilize HAL methods and as such run unprivileged. The rationale for gnome-mount is to have a centralized place (in GConf) where settings such as mount options and mount locations are maintained. [4] As with all unix-like commands, the options are specific to the version of mount and are precisely detailed in its man ...
Version 2.x is a newer, redesigned, and reimplemented one. aufs is an alternative version of unionfs. [7] overlayfs written by Miklos Szeredi has been used in OpenWRT and considered by Ubuntu and has been merged into the mainline Linux kernel on 26 October 2014 [8] after many years of development and discussion [9] for version 3.18 of the kernel.
The need and specification of a kernel mode Linux union mount filesystem was identified in late 2009. [1] The initial RFC patchset of OverlayFS was submitted by Miklos Szeredi in 2010. [2] By 2011, OpenWrt had already adopted it for their use. [3] It was merged into the Linux kernel mainline in 2014, in kernel version 3.18.
A mount point is a location in the partition used as a root filesystem. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives.
In the Linux kernel, the fat, hfs, hpfs, ntfs, and udf file system drivers support a umask mount option, which controls how the disk information is mapped to permissions. This is not the same as the per-process mask described above, although the permissions are calculated in a similar way.
The effective UID (euid) of a process is used for most access checks.It is also used as the owner for files created by that process. The effective GID (egid) of a process also affects access control and may also affect file creation, depending on the semantics of the specific kernel implementation in use and possibly the mount options used.
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.
