The box file size doesn't increase by creating a larger disk partition by
default; it dynamically resizes to grow as space is used within the VM.

"For example, in VirtualBox, you should create a dynamically resizing drive
with a large maximum size. This causes the actual footprint of the drive to
be small initially, but to dynamically grow towards the max size as disk
space is needed, providing the most flexibility for the end user."

I'm not aware of any method for automatically resizing the disk of a base
box. See e.g.
http://askubuntu.com/questions/317338/how-can-i-increase-disk-size-on-a-vagrant-vm/318711#318711
for a workaround -- but I'd definitely not push that onto e.g. web
developers using these VMs, and if I'd have to save my own box image, I'd
just create one from scratch in the first place.

Am I missing some method for resizing the image easily on the fly?  If so,
that seems to contradict the Vagrant docs.
