**mergerfs** is similar to **mhddfs**, **unionfs**, and **aufs**. Like **mhddfs** in that it too uses **FUSE**. Like **aufs** in that it provides multiple policies for how to handle behavior.
Why create **mergerfs** when those exist? **mhddfs** has not been updated in some time nor very flexible. There are also security issues when with running as root. **aufs** is more flexible than **mhddfs** but contains some hard to debug inconsistencies in behavior on account of it being a kernel driver. Neither support file attributes ([chattr](http://linux.die.net/man/1/chattr)).
Why **mergerfs** when those exist? **mhddfs** has not been updated in some time nor very flexible. There are also security issues when with running as root. **aufs** is more flexible than **mhddfs** but kernel based and difficult to debug when problems arise and slower to evolve as a result. Neither support file attributes ([chattr](http://linux.die.net/man/1/chattr)).
