check if guifi drupal6 volumes are working as expected

[ghost]

I think after first build sometimes is not working anymore (?)

/usr/share/drupal/guifi-web directory becomes empty

[Sun Aug 27 08:46:57.088736 2017] [autoindex:error] [pid 32] [client 172.18.0.1:42144] AH01276: Cannot serve directory /usr/share/drupal/guifi-web/: No matching DirectoryIndex (index.php) found, and server-generated directory index forbidden by Options directive

I see that this link "propose a solution" http://wade.be/development/2016/05/02/docker.html

This a early bug reporting. If I'm not experimenting this after some time I will close. If not, I will continue reporting problems until I can reproduce or fix it
