Config should be in a volume

[AlbanBedel]

While trying to move an install from one machine to another the new instance kept going into the installer although I copied all the volumes to the new machine. It turns out that some configuration is stored in /app/application/config, but it is not defined as a volume.

This is with crramirez/limesurvey:2 but that might also apply to version 3.

Hello yes, you are right. I tried to put it in a volume but the results were worse. I don't know what else is needed to be back up in order to keep all the configuration.
