vagrant becoming root on login stalls vagrant-hostmanager

[Eimert]

Issue
Vagrant is stuck at the step '==> buildserver: Updating /etc/hosts file on active guest machines...'.

Cause
I added echo "sudo -i" >> /home/vagrant/.bashrc to my provisioner script. My aim is to become root after login. It seems that the vagrant-hostmanager plugin cannot handle this (yet); After removing the sudo -i line, vagrant works just fine.

Tried a workaround
Putting the vagrant-hostmanager plugin as the last step didn't work either, because I have three machines and the plugin cannot update the /etc/hosts file on the first machine (since that machine does a sudo -i on login).

Reproduction
The issue can be reproduced by doing a vagrant up on the attached Vagrantfile and provisioner script.

Possible fix: adding sudo -i to $HOME/.bash_profile, since that file is only loaded on interactive logins.
