 # config.vm.synced_folder ".", "/vagrant", disabled: true
 # config.vm.synced_folder ".", "/home/vagrant/provision", type: "rsync"
 config.vm.provider :virtualbox do |vb|
 # Set VM memory size
 vb.customize ["modifyvm", :id, "--memory", "512"]
 # these 2 commands massively speed up DNS resolution, which means outbound
 # connections don't take forever (eg the WP admin dashboard and update page)
