When things go wrong, especially during stressful operations like reinstall and upgrade configuration files, 24x80 is IMnsHO inadequate and scrollback is really, really useful. At those times tmux or other layers are not easily available - /usr may not be mountable yet, the net is almost certainly off because pf hasn't been configured correctly yet, and it's quite likely there's no other machine around to use for a serial console. Please keep us posted on the font metric changes. 50x would be a lot better but still very much less than the current 100 or more scrollback lines.
How early in the boot process would the font metric change capabilities be accessible? Could a boot-time or config option work? I'd be very glad to test and help debug anything in this area. thanks Geoff Steckel
