SNO Quickstart doc questions

[webbnh]

The SNO quickstart doc says:

We can now set the ssh vars in the ansible/vars/all.yml file since setup-bastion.yml has completed. For bare metal clusters only ssh_public_key_file is required to be filled out. The recommendation is to copy the public ssh key file from your bastion local to your laptop and set ssh_public_key_file to the location of that file. This file determines which ssh key will be automatically permitted to ssh into the cluster's nodes.

It mentions "For bare metal clusters"...should that say "For SNO clusters"?

It mentions copying the public ssh key file from the bastion to your laptop and then setting the variable to point to that file...if I'm running everything on the bastion, why would I want to point to a file on my laptop? In the BM quickstart, there is no analogous advice between the steps for setup-bastion and bm-deploy...are the comments here obsolete? (At this point, the value of ssh_public_key_file is already set to ~/.ssh/id_rsa.pub which looks reasonable for execution on the bastion.)
