为什么Vagrant在运行流浪销毁后会要求你重新安装插件？

Question

我使用的是Vagrant SSHFS插件，而不是rsync。我安装了插件：

vagrant plugin install vagrant-sshfs

下面是我的Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "debian/jessie64"
  config.vm.synced_folder "./live-build", "/home/vagrant/live-build", type: "sshfs"
  config.vm.provision "shell", path: "./provision/setup.sh"
  config.vm.provision "shell", path: "./provision/build.sh"
end

当我运行vagrant up时，主机的live-build目录是链接的，并且我可以看到来宾系统中的文件。

现在，如果我运行：vagrant destroy，然后vagrant up synced_folder尝试缺省为rsync，这将导致以下错误：

Host path: /Users/jake/OZYProject/
Guest path: /vagrant
Command: "rsync" "--verbose" "--archive" "--delete" "-z" "--copy-links" "--no-owner" "--no-group" "--rsync-path" "sudo rsync" "-e" "ssh -p 2222 -o LogLevel=FATAL  -o ControlMaster=auto -o ControlPath=/var/folders/lp/qxycffd53lxdhbhvy34lymrh0000gn/T/ssh.180 -o ControlPersist=10m  -o IdentitiesOnly=yes -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i '/Users/jake/OZYProject/.vagrant/machines/default/virtualbox/private_key'" "--exclude" ".vagrant/" "/Users/jake/OZYProject/" "vagrant@127.0.0.1:/vagrant"
Error: symlink has no referent: "/Users/jake/OZYProject/whonix-live-build/config/hooks/0010-disable-kexec-tools.hook.chroot"
...

奇怪的是插件已经安装好了：

vagrant plugin list
vagrant-share (1.1.6, system)
vagrant-sshfs (1.3.0)
vagrant-vbguest (0.14.2)

如果我尝试安装vagrant plugin install vagrant-sshfs (即使它已经安装)并重试vagrant up，它将使用sshfs正确安装。似乎我必须在运行destroy之后安装vagrant-sshfs。

这是正常的吗？
