This basically adds a docker label support. Which is required for all RHEL base images ;-)

This actually does not work: the assert expects the keys are options from image-build section, but this loop expects to get those options nested in another repo.

Why all the redundant data?

Fixed yo guys!

This line needs to be updated to _set_release(image_conf['image-build']).

_get_install_tree should be called with image_conf['image-build']

First argument to _get_repo needs to be updated.

This needs to check keys in config_options['image-build'], otherwise it checks the keys against section names.

I don't have a line in the diff to put this to: pungi/phases/image_build.py:130 needs image_conf['image-build'] to get scratch correctly

I have rebased the patch to master, resolved conflicts and added a commit fixing the tests in pull request 145.
