Arangodb: --database.directory setting not respected when giving instance a name
<p>When I run arangod like this:  </p>

<pre><code>arangod --supervisor --daemon --pid-file some_file \
        --configuration some_file.conf \
        single_instance
</code></pre>

<p>then </p>

<pre><code>--database.directory
</code></pre>

<p>option is ignored and </p>

<pre><code>/var/tmp/single_instance
</code></pre>

<p>directory containing </p>

<pre><code>├── single_instance_db
    ├── databases
    ├── journals
    ├── LOCK
    ├── rocksdb
    ├── SERVER
    └── SHUTDOWN
</code></pre>

<p>is created.  </p>

<p>But when I run arangod like this:</p>

<pre><code>arangod --supervisor --daemon --pid-file some_file \
        --configuration some_file.conf
</code></pre>

<p>then </p>

<pre><code>--database.directory
</code></pre>

<p>option is honoured.</p>

<p>Why ?<br>
(Is it some bug ?)</p>
