It looks like when I run “vagrant up” it will add the host to my /etc/hosts file even if there is one already and there appear to be duplicates. Is that correct? Is it advisable to delete the old ones?
UPDATE: This is working correctly. Vagrant up adds the host. Vagrant halt removes the host. Unknown as to why I had duplicate hosts listed in my /etc/hosts file or if it was potentially causing any problems. If you see duplicates, you can manually edit.
