Vagrant is a tool for building and distributing development environments.

Vagrant::Environment#copy_insecure_private_key

This method copies the private key into the home directory if it
doesn't already exist.

This must be done because `ssh` requires that the key is chmod
0600, but if Vagrant is installed as a separate user, then the
effective uid won't be able to read the key. So the key is copied
to the home directory and chmod 0600.
