Binary package “aufs-tools” in ubuntu xenial

Tools to manage aufs filesystems

 The aufs driver provides a unification file system for the Linux kernel. It
 allows one to virtually merge the contents of several directories and/or stack
 them, so that apparent file changes in the aufs end in file changes in only one
 of the source directories.
 This package contains utilities needed to configure aufs containers on-the-fly.
