Thanks, that's helpful and a reasonable explanation. Is Facter similar to
Chef's Ohai? Anyway, it looks like this Vagrant box has Facter 1.6.18. I'll
have to double check with my coworker that he is indeed using the same
Vagrant box, but since we're getting our Vagrantfile from the same Chef
repo, I doubt he'd have a different version, and yet he doesn't have the
issue when running a $ vagrant provision. He's out today but I'll follow up
with him as soon as possible.
