In the early days, aufs was entirely re-designed and re-implemented Unionfs Version 1.x series. Introducing many original ideas, approaches and improvements, it becomes totally different from Unionfs while keeping the basic features. if AUFS_FS choice prompt "Maximum number of branches" default AUFS_BRANCH_MAX_127 help Specifies the maximum number of branches (or member directories) in a single aufs.
