syncd - A simple solution for synchronizing changes to your vagrant box
vagrant is great when it comes to pre-configuring reproducible, and portable development environments for Drupal - in particular in combination with Ansible. However with sites of a decent size the performance of Drupal projects running on the NFS share vagrant uses for shared folders has become more and more of an issue - at least with Virtualbox. syncd forms a simple, pre-configurable solution that automatically syncs changes into the vagrant box, such that the files can be served from the regular VM filesystem instead.
