Is rsync up to and including 1.6.3 only one-directional?

[JimOser]

Just to clarify is rsync up to and including 1.6.3 only one-directional?

https://github.com/mitchellh/vagrant/blob/master/CHANGELOG.md
states:

New synced folder type: rsync - Does a one-time one-directional sync to the guest machine. New commands vagrant rsync and vagrant rsync-auto can resync the folders.

Are all the other rsync changes up to and including 1.6.3 also only referring to sync being one-directional sync?

Also https://github.com/mitchellh/vagrant-aws/blob/f8525a265a83aa2d32e25c46f1ceae6f82d887a4/README.md

first mentions:

Minimal synced folder support via rsync.

then later states:

There is minimal support for synced folders. Upon vagrant up, vagrant reload, and vagrant provision, the AWS provider will use rsync (if available) to uni-directionally sync the folder to the remote machine over SSH.

http://docs.vagrantup.com/v2/synced-folders/index.html
states:

Synced folders enable Vagrant to sync a folder on the host machine to the guest machine, allowing you to continue working on your project's files on your host machine, but use the resources in the guest machine to compile or run your project.

However:
#3062

has 2 solutions to make syncing bidirectional:

2. Alex Rodionov

vagrant ssh-config > vagrant-ssh-config
rsync --archive -z --exclude .vagrant/ --exclude Vagrantfile --exclude .git --exclude tmp --exclude .bundle -e 'ssh -F vagrant-ssh-config' default:/vagrant/ .
rm vagrant-ssh-config

The above is probably also related to:

#4111

[mitchellh]

The rsync in Vagrant is currently one directional.

is anyone planning on making it two way for 1.6+ or 1.7?
