Hello Bruce,

unfortunately, there is not a single warning or error message whatsoever 
thrown. The first occasion, some error message is thrown, occurs during 
do_rootfs where it complains about the missing package "docker" - which is 
obviously missing as it has not been build.

As I mentioned in my original post, the docker package is being built when 
using the rpm backend though.

I've never seen this, but then again, I've also never used the .deb package 

When you were building with .debs, and your image had "docker' in the image 
install .. was there any errors thrown due to the package not being created ?
