Vagrant synced_folder id option

The syntax for enabling an NFS folder share in Vagrant is commonly posted as:

config.vm.synced_folder "<HOST_DIR>", "<VM_DIR>", id: "???", type: "nfs", mount_options: ["nolock", "vers=3", "udp"]

Note the id argument. I've read the Vagrant docs at https://docs.vagrantup.com/v2/synced-folders/basic_usage.html, but this option isn't mentioned.

Given its frequent use in Vagrantfiles, I assume this option is relevant, if not mandatory. What exactly does it do?

When using the default VirtualBox shared folder mechanism, the id option will be what appears when you list your mount points in the guest OS using mount. For example:

Vagrantfile

config.vm.synced_folder "<HOST_DIR>", "/opt/bar", id: "foo"

Guest OS via SSH

$ mount
...
foo on /opt/bar type vboxsf (uid=1000,gid=1000,rw)

I have not tested whether the id option is used for nfs synced folders, but I can confirm that it has no bearing on rsync synced folders.
