Saving changes
--------------
If you are using OS X or Windows, you need to create a /data partition inside the
virtual machine that runs the docker deamon in order make all changes persistent.
If you don't do that your /data directory will get wiped out on every reboot.
To create a persistent folder, log into the virtual machine by running:
::
$ docker-machine ssh dev1
$ sudo su
$ echo 'ln -sfn /mnt/sda1/data /data' >> /var/lib/boot2docker/bootlocal.sh
In case you are wondering why you can't use a host volume to keep the files on
your mac: As of `boot2docker` 1.7 you'll run into permission problems with mounted
host volumes if the container creates his own user and chown's the directories
on the volume. Postgres is doing that, so we need this quick fix to ensure that
all development data persists.
