vagrantでdebian/jessieをvagrant cloudを利用して立ち上げたのですがsynced_folder 機能がリアルタイムで反映されなくて困っています.
対してubuntu/trusty64ではsynced_folder 機能がリアルタイムで反映されるので余計に謎が深まっています.(こちらもvagrant cloudを利用しています)
debian/jessieにおけるsynced_folderの挙動ですが,ホスト側のsynced_folderで設定しているディレクトリの中身をゲスト側のディレクトリへ上書きするようになってしまっています.上書きタイミングはvagrant upもしくはvagrant reloadです.

synced_folderうまくいく場合:

両方共にconfig.vm.synced_folderのコメントを外しております.

debian/jessieのログに

==> default: Rsyncing folder: /Users/hoge/Vagrant/debian-jessie64/ => /vagrant

とあることから、rsyncタイプでsynced_folder機能が立ち上がっていると思われます。

rsyncタイプは"ホスト"->"ゲスト"の一方向のファイル共有なので、

ホスト側のsynced_folderで設定しているディレクトリの中身をゲスト側のディレクトリへ上書きするように

なります。
https://www.vagrantup.com/docs/synced-folders/rsync.html

The rsync synced folder does a one-time one-way sync from the machine running to the machine being started by Vagrant.

で、debian/jessieのチェンジログを見てみると、v8.2.2 で
「デフォルトの共有タイプをrsyncに変更した」
とあります。
https://atlas.hashicorp.com/debian/boxes/jessie64

switch to rsync as default method for synced folders, because vboxfs requires contrib or non-free packages

というわけで、以下のいずれかの方法でうまく行くか、試してみてください。
(恐縮ですが、私の手元に環境が無いため、当方では未検証です)

1.

synced_folderの設定を以下のように変更する。

Before
config.vm.synced_folder "./", "/vagrant"
After
config.vm.synced_folder "./", "/vagrant", type: "virtualbox"

または

config.vm.synced_folder "./", "/vagrant", type: "nfs"

2.

config.vm.synced_folder "./", "/vagrant", type: "virtualbox"に加えて、boxを以下のように変更する。

Before
config.vm.box = "debian/jessie64"
After
config.vm.box = "debian/contrib-jessie64"

https://atlas.hashicorp.com/debian/boxes/contrib-jessie64/

3.

config.vm.synced_folder "./", "/vagrant", type: "nfs"に加えて、ホストマシンに nfsd をインストールする。
https://www.vagrantup.com/docs/synced-folders/nfs.html

Before using synced folders backed by NFS, the host machine must have nfsd installed, the NFS server daemon.

具体的な手順は、、
不勉強のため、私には分かりません(^^;

「config.vm.synced_folder "./", "/vagrant", type: "virtualbox"」とオプションを追加したところ, ==> default: Mounting shared folders... default: /vagrant => /Users/hoge/Vagrant/debian-jessie64 となり,うまくいきました!ありがとうございます!
