aufs
开发者Junjiro Okajima英语Junjiro Okajima
全称Advanced multi layered unification filesystem
发布2006年
功能
文件系统权限POSIX
操作系统支持Linux,通过第三方内核模块

aufs(全称:advanced multi-layered unification filesystem高级多层统一文件系统)用于为Linux文件系统实现联合挂载英语Union mount。该名称最初是AnotherUnionFS首字母缩略字,但从第2版开始它代表“advanced multi-layered unification filesystem”。

aufs是之前的UnionFS英语UnionFS的完全重写,2006年由冈岛顺治郎英语Junjiro Okajima开发[1]。它旨在提高可靠性和性能,但也引入了一些新概念,例如可写分支平衡[2]和其他改进——其中一些目前已在UnionFS 2.x分支中实现。

aufs被拒绝合并到主线Linux。它的代码被批评为是“稠密,不可读,无注释”。[3]相反,OverlayFS已被合并到Linux内核。[4][5]在数次尝试后,作者已经放弃。[6]

使用

Docker最初使用aufs作为容器文件系统层。它目前仍作为存储后端之一来支持。

数个Linux发行版已选择aufs作为UnionFS的替代品,包括:
