title: Cannot change permissions of folders within vagrant home folder
body: <p>When I ssh in to my vagrant vm, I can change permissions of files and folders above and outside the vagrant user folder, and for files within the vagrant user folder. But cannot change permissions for folders under the vagrant user folder. I have the same problem whether logged in as the vagrant user and root.</p>
  
  <p>Is there some sort of restriction on changing permissions in the vagrant user's folder? The vagrant user folder is not shared with the host OS, but the capistrano deploy folder and the docRoot are. </p>
  
  <p>Guest is CentOS 6, Host is OS X 10.7. Vagrant is 1.0.5. Virtualbox is 4.2.1.</p>
