I'm facing an odd problem with (re)packaging a Vagrant box and hope that maybe someone can tell me in what direction to look. This is the story

* I installed Vagrant and have successfully created some puppet manifests and it all works fine, vagrant up ... provisioning, ...
* Then I needed to switch to NFS which failed because nfs was not installed on my Guest OS (Ubuntu 11.04-amd64)
* I installed nfs-common on the guest OS (`sudo apt-get install nfs-common`)
* `vagrant halt`
* `vagrant up`
* And the NFS mount works flawlessly, even after several halt/up commands, I'm happy!

The next logical step would be packaging the box so I do not need to reinstall nfs-common each time the VM is destroyed.

* In the same directory as above : `vagrant package`
* `vagrant box add ubuntuvm2 package.box`
* `rm package.box`
* change the line `config.vm.box` in Vagrantfile to ubuntuvm2
* `vagrant destroy`
* `vagrant up`
* and all of a sudden the nfs mount fails, when sshing into the VM i can confirm that nfs-common is indeed installed but the NFS mount just fails: <https://img.skitch.com/20120302-kwix296t44y31rxkd52pwm72f4.jpg>

Anyone has an idea in what direction to start looking for a solution?

I'm using Virtualbox 4.1.8 and Vagrant 1.0.0 on OS-X Lion
