@GeoDerp Could it be possible to take a look at this when you have some spare time?
It seems like a bug to me.
In the old days we were copying these type of files "manually" in the Dockerfile but now I'm a bit lost with our current version of the Dockerfile, it exceed my skills

Well I may have overreacted ;-)
This seems like an easy fix. Do you confirm @GeoDerp? See #452
