usage

1. demo

   1. from github

       Vagrant.configure("2") do |config|
         config.vm.box = 'your-box'
         if Vagrant.has_plugin?("vagrant-cachier")
           # Configure cached packages to be shared between instances of the same base box.

           # OPTIONAL: If you are using VirtualBox, you might want to use that to enable
           # NFS for shared folders. This is also very useful for vagrant-libvirt if you
           # want bi-directional sync
           config.cache.synced_folder_opts = {
             type: :nfs,
             # The nolock option can be useful for an NFSv3 client that wants to avoid the
             # NLM sideband protocol. Without this option, apt-get might hang if it tries
             # to lock files needed for /var/cache/* operations. All of this can be avoided
             # by using NFSv4 everywhere. Please note that the tcp option is not the default.
             mount_options: ['rw', 'vers=3', 'tcp', 'nolock']
           }
