Fix hanging NFS mount on Ubuntu 14.04 when calling `vagrant up`
NFS mounts have been known to hang when running
vagrant up on Ubuntu. This is commonly caused by issues with using the
udp protocol for the NFS mount.
Version 1.4.0+ of Vagrant added a new
nfs_udp option. I was able to add
nfs_udp: false to my
config.vm.synced_folder options to fix the issue.
config.vm.synced_folder "repositories", "/home/vagrant/repositories", type: "nfs", nfs_udp: false
