A union mount is a mount that allows several filesystems to be mounted at one time, appearing to be one filesystem.
Generally one of the filesystems will be mounted read-write, while other filesystems are mounted read-only.
Union mounts are implemented by a union filesystem such as UnionFS and AUFS.
