Vagrant Synced Folder Defaults: Transitioning Between Providers in Version 2
Goal To understand how the default synced‑folder type in Vagrant 2.x changes when switching providers and what explicit configuration is required to maintain consistent behavior. Constraints Vagrantfile must use config version 2 – mixing version 1 and 2 is unsupported. Different providers (VirtualBox, NFS, SMB, rsync) apply distinct default sync mechanisms.
