### Dynamic Daemon / Client-only Binary
If you are only interested in a Docker client binary, set `DOCKER_CLIENTONLY` to a non-empty value using something similar to the following: (which will prevent the extra step of compiling dockerinit)
```bash
export DOCKER_CLIENTONLY=1
```
If you need to (due to distro policy, distro library availability, or for other
reasons) create a dynamically compiled daemon binary, or if you are only
interested in creating a client binary for Docker, use something similar to the
