apt-get update
apt-get upgrade

# I had no idea that you could do this:
def attribute(name, type = Ohm::Types::String, klass = Ohm::Types[type])
# If no 3rd argument is provided then it uses the second argument to key
# the default value. Not super obvious, but now that I know about it, I
# think it's kinda cool :-)
