Reports "Permission denied" but /etc/hosts is updated only when "sudo vagrant up" is used, not as normal user. #212

Platform: OSX 10.11.6 (El Capitan), Vagrant 1.8.5,

I have setup my account ("dan") in the /etc/sudoers so it can modify the /etc/hosts file:

Cmnd_Alias VAGRANT_HOSTMANAGER_UPDATE = /bin/cp /Users/dan/.vagrant.d/tmp/hosts.local /etc/hosts
dan ALL=(root) NOPASSWD: VAGRANT_HOSTMANAGER_UPDATE

When I run a simple vagrant up on this Vagrantfile:

Vagrant.configure("2") do |config|
  config.hostmanager.enabled = true
  config.hostmanager.manage_host = true
  config.vm.box = "centos/6"
  config.vm.hostname = "myhost"
end

The run fails:

==> default: Updating /etc/hosts file on active guest machines...
==> default: Updating /etc/hosts file on host machine (password may be required)...
==> default: Forcing shutdown of VM...
==> default: Destroying VM and associated drives...

If I manually run sudo /bin/cp /Users/dan/.vagrant.d/tmp/hosts.local /etc/hosts as my dan user the /etc/hosts file is updated from the generated hosts.local.
