changing project.package_name instead of project.name

was wondering what you thought of changing the project.name back to gitlab (which should allow us to take out the package_scripts path override in project.rb)

And instead having project.package_name set to gitlab-ce/gitlab-ee

I'm looking at making the command-names and install-dir more configurable #{project.name}-ctl for example. So we can use all the same code but different project.rb to build a gitlab fork. Might be a start for managing multiple gitlab instances on the same box as well.
