Create and install Ubuntu 12.04 server Vagrant base box.
This initial version is tested and working on Ubuntu Desktop 12.10. Swap in the "headless" lines to run it on Ubuntu server.
A few packages are required
$ sudo ./apt.sh
This will download the Ubuntu 12.04 server ISO, create a VM ubuntu-precise-32, package and install a Vagrant base box of the same name. Any existing VM and base box with that name will be deleted first.
This is my take on cal/vagrant-ubuntu-precise-64
