// * Pluggable storage drivers including aufs, vfs, lvm and btrfs.
// * Pluggable execution drivers including lxc and chroot.

// In practice `daemon` still includes most core Docker components, including:
//
// * The reference registry client implementation
// * Image management
// * The build facility
// * Logging
//
// These components should be broken off into plugins of their own.
