# Providers were added on Vagrant >= 1.1.0
#
# NOTE: The vagrant "vm.provision" appends its arguments to a list and executes
# them in order. If you invoke "vm.provision :shell, :inline => $script"
# twice then vagrant will run the script two times. Unfortunately when you use
# providers and the override argument to set up provisioners (like the vbox
# guest extensions) they 1) don't replace the other provisioners (they append
# to the end of the list) and 2) you can't control the order the provisioners
# are executed (you can only append to the list). If you want the virtualbox
# only script to run before the other script, you have to jump through a lot of
# hoops.
#
# Here is my only repeatable solution: make one script that is common ($script)
# and another script that is the virtual box guest *prepended* to the common
# script. Only ever use "vm.provision" *one time* per provider. That means
# every single provider has an override, and every single one configures
# "vm.provision". Much saddness, but such is life.
