is there a config setting I can access to change the default on a live server ( for remote maintenance, I'd like to change what the customers see? )
If you want the console to show without logging in (deprecated for security reasons), then you can have it:
config set ConsoleMode auto
signal-event post-upgrade
signal-event reboot
or, if you wish to avoid the reboot
config set ConsoleMode auto
expand-template /etc/inittab
telinit q
