@Alexander-Pitzer A docker image would be most convenient! But that's something the community could do, once the .config is known (plus maybe some stuff for /files).
Figuring out the right .config by reverse engineering however would be really tedious and completely redundant work, because that .config already does exist - only it's not available! So I still hope Onion will decide to publish it! Any chances for that, @Lazar-Demin?
