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.
