Disclaimer after the OPNsense logo and before the Login prompt?

[anomaly0617]

I've been asked by management to add a disclaimer between the OPNsense logo and the Login prompt. The disclaimer is their boilerplate "This is a government/commercial institution device, hacking is a crime and you really shouldn't be here if you aren't supposed to be here, blah blah" message that we have on all the PCs when you press Control-Alt-Delete and before the login prompt appears. This is for the HDMI/VGA console and the SSH console, not the Web UI (though they may want that too eventually).

Is there an easy way for me to add this verbiage to the login screen? In linux I think this is /etc/motd, but I'm not sure what it is on OPNsense/FreeBSD.

Thanks, in advance!

I see that there exists /var/run/motd, which I accessed via SSH.
