Comment:
Just create a script to prepare the build env inside the docker container on start. 

You can create a non-root user, clone void-packages and run binary-bootstrap. 

Then create /tmp/bootstrapped (or alike) so you know when its finished and run your builds inside.

(Of course, if you make a persistant container you gotta pull from remote origin). 

Maybe I'm missing the point here?
