Of the learning environments that leverage Ansible, very few are using roles. This can make porting Ansible playbooks across learning environments more difficult. To fix this, Ansible-using learning environments need to be refactored (where possible) to use an Ansible role.

Remove usages of MAGMA_ROOT env var from swaggergen and combine_swagger executables, since it can break tests when run on host machines and is unnecessary coupling to repo structure.

In the course of implementation, will also need to update the golden files to use the localized tmp directory instead of MAGMA_ROOT.

This is a bit heftier of a bootcamp task, but it should be achievable.

Some old programs versions can be found here if someone needs them to test old exploits for instance.
