### Daemon storage-driver option
The Docker daemon has support for several different image layer storage drivers: `aufs`,
`devicemapper`, `btrfs` and `overlay`.
`devicemapper`, `btrfs`, `zfs` and `overlay`.
The `aufs` driver is the oldest, but is based on a Linux kernel patch-set that
is unlikely to be merged into the main kernel. These are also known to cause some

The `btrfs` driver is very fast for `docker build` - but like `devicemapper` does not
share executable memory between devices. Use `docker -d -s btrfs -g /mnt/btrfs_partition`.
The `zfs` driver is probably not fast as `btrfs` but has a longer track record
on stability. Thanks to `Single Copy ARC` shared blocks between clones will be
cached only once. Use `docker -d -s zfs`. To select a different zfs filesystem
as backingstore use the storage option `zfs.fsname`:
`docker -d -s zfs --storage-opt zfs.fsname=zroot/docker`
The `overlay` is a very fast union filesystem. It is now merged in the main
Linux kernel as of [3.18.0](https://lkml.org/lkml/2014/10/26/137).
Call `docker -d -s overlay` to use it.
