So we have --ssh-user covered here, but even though --ssh-password is in the options above, it does not seem to be used in the config. Given that there is also no way to specify an ssh key, this implies that authentication must be username / password, so in order to bootstrap, we need to use the password.
Is omission of password in bootstrap config intentional, and if so, why is it in options above? If it is not supposed to be used at all, how does this command authenticate to the node to be bootstrapped given that there seems to be no way to specify credentials?
