Git config is weirdly synchronized between host and guest

[LeBenLeBen]

If you use Git to commit inside the Vagrant box, you end-up with a commit signed by "Vagrant User" instead of your name/email configured in your host git config.

Reproduction Steps:

1. Create a blank box with the role Git
2. Commit something inside the box: git commit -m "Test" --allow-empty
3. The commit is signed by "Vagrant User" with a generated email depending on the project name

Expected behavior:

The commit should be signed with the same config as my host Git config.

Observed behavior:

The role git seems to correctly set the config in the guest at /etc/gitconfig. However, another git config is created at ~/.gitconfig. I tried to delete this file but everytime I run a git command, this file gets recreated with an empty "name" and "email" field. I was able to make it work by removing the empty "name" and "email" fields from the ~/.gitconfig file. It then fallback to the /etc/gitconfig values which are the expected ones.

Drifter version: 1.4.0
Vagrant version: 1.9.5
OS and version: MacOS 10.12.6

Additional information:

• Problem started happening recently, didn't happen in an older version of Drifter: I think so, it might comes from a new version of Git or differences in the base boxes
• Problem can be reliably reproduced, doesn't happen randomly: Yes
• Problem happens to my colleagues aswell or only me: Yes

Ok this nearly killed me but I finally found out the problem doesn't come from the provisioning, but from the base boxes themselves, and more specifically the way we build them. I filed an issue on the drifter-base-boxes repository.

I'll keep this issue open until the problem is fixed upstream and post any updates here.
