Yes. Even with StrickHostKeyChecking=no, if you don't blow away known
hosts you'll get a nasty warning message. And if you just do the
known-hosts delete, you'll get a prompt to add the new key on each
connect. So the combination does the trick. Of course, this is a
controlled test environment. Don't do this at home, kids...
