Comment 80 for bug 1569237

You shouldn't have to use vagrant ssh. See https://www.vagrantup.com/docs/boxes/base.html#quot-vagrant-quot-user

To quote that page
> Just about every aspect of Vagrant can be modified. However, Vagrant does expect some defaults which will
> cause your base box to "just work" out of the box. You should create these as defaults if you intend to
> publicly distribute your box.

> By default, Vagrant expects a "vagrant" user to SSH into the machine as. This user should be setup with the > insecure keypair that Vagrant uses as a default to attempt to SSH

Why isn't this honored?
