An old version of VirtualBox does not support a configuration key used in the Vagrantfile to build a parent image from which my recommended base box is derived. I'm wondering if there is someway we might disable that in our base image, before it crashes the legacy VirtualBox version.
I cannot seem to find my notes (from two nights ago when working on a colleague's machine, with virtualbox 4.3 installed from his aptitude packaging). But it is the configuration key which when set, on my 5.2 installation successfully builds and generates this message: ==> default: Machine 'default' has a post `vagrant up` message. This is a message ==> default: from the creator of the Vagrantfile, and not from Vagrant itself: ==> default: ==> default: Vanilla Debian box.
