To run the daemon with `systemd socket activation <http://0pointer.de/blog/projects/socket-activation.html>`_, use ``docker -d -H fd://``.
Using ``fd://`` will work perfectly for most setups but you can also specify individual sockets too ``docker -d -H fd://3``.
If the specified socket activated files aren't found then docker will exit.
You can find examples of using systemd socket activation with docker and systemd in the `docker source tree <https://github.com/dotcloud/docker/blob/master/contrib/init/systemd/socket-activation/>`_.
+.. warning::
+ Docker and LXC do not support the use of softlinks for either the Docker data directory (``/var/lib/docker``) or for ``/tmp``.
+ If your system is likely to be set up in that way, you can use ``readlink -f`` to canonicalise the links:
+
+ ``TMPDIR=$(readlink -f /tmp) /usr/local/bin/docker -d -D -g $(readlink -f /var/lib/docker) -H unix:// $EXPOSE_ALL > /var/lib/boot2docker/docker.log 2>&1``
