This directory contains various Docker-friendly Vagrant base boxes, built
by Phusion. There are boxes based on Ubuntu 12.04 64-bit, and
boxes based on Ubuntu 14.04 64-bit. They differ from the ones provided by
vagrantup.com in the following ways:

 * We provide 2 virtual CPUs by default, so that the boxes can make better
   use of multicore hosts.
 * We provide more RAM by default: 1 GB.
 * We provide a bigger virtual hard disk: around 40 GB.
 * We use LVM so that partitioning is easier.
 * On the Ubuntu 12.04 version, our default kernel version is 3.8 (instead
   of 3.2), so that you can use [Docker](http://www.docker.io/) out-of-the-box.
 * The memory cgroup and swap accounting are turned on, in order to make some
   Docker features usable. See http://docs.docker.io/en/latest/installation/ubuntulinux/#memory-and-swap-accounting
 * Chef is installed via the Ubuntu packages that they provide, instead of
   via RubyGems. This way the box doesn't have to come with Ruby by default,
   making the environment cleaner.
 * Our VMWare Fusion boxes recompile VMWare Tools on every kernel upgrade,
   so that Shared Folders keep working even if you change the kernel.
