Vagrant version

Vagrant 1.8.1

Expected behavior

No systemd output, mounts correctly

Actual behavior

Spurious systemd buffered output stopping NFS provisioning; if ctrl+c then it also stops vagrant provisioning and mounts don't finish. If pressing Q, systemd buffer finishes correctly and mounts mount.

Steps to reproduce

1. Install Ubuntu 16.04 from daily cd image+ latest vagrant + nfs kernel server
2. Try run that vagrantfile
3. Voila
