Does anybody _actually_ use the HashiCorp stack, besides Vagrant, for serious work? I tried and honestly found their products sorely, sorely lacking. Very shiny documentation, very incomplete, un-battled-tested tools, no examples given, little response from their devs other than the PR team.
For a small example, I _still_ get +1 notifications on this critical issue nearly every day: https://github.com/mitchellh/packer/issues/409 - no response from dev team whatsoever.
