Dependencies installation

[pomarec]

When i create a virtualenv and install arkos-core it does not install some dependencies correctly (pycryptsetup & pyparted).

pip install -e git+https://github.com/arkoscloud/core.git#egg=arkosctl
Obtaining arkosctl from git+https://github.com/arkoscloud/core.git#egg=arkosctl
  git clone in ./.venv/src/arkosctl exists with URL https://github.com/pomarec/core.git

  Running setup.py (path:/home/deploy/test/.venv/src/arkosctl/setup.py) egg_info for package arkosctl produced metadata for project name arkos-core. Fix your #egg=arkosctl fragments.

My investigation lead me to understand few things :

• you should use --process-dependency-links with the pip install
• BUT this feature is deprecated as we speak and is in process for being put back in pip

Cloning the repo and running python setup.py install works but then we miss some dependencies :

 arkosctl

Yeah, the distribution of modules that are forked or otherwise not available on PyPI is not optimal at the moment. It's not clear what the preferred way of setuptools is to handle this issue, either. Needs more research!
