Easiest path is to just add

    ;; Allow root login to allow easy login before you set up your
    ;; initial password for sudo purposes.  You can remove this line
    ;; after you log in and set your initial user password.
    ("root" ,(local-file "janedoe_rsa.pub")

after the janedoe thing and delete that whole paragraph.  That provides
an easyish way to deal with things... if someone is uncomfortable with
having a root login, I suppose they have enough experience to know how
to remove this later if they want.

Great work on this, with that change I think it looks good to go!
