Somewhat broken serial console on beta

[pharlock]

All full beta builds i have tried (ie not tried nano/embedded) i get dumped to a shell prompt, no menu.

You could try edit /etc/ttys and change dialup to cons25

ttyu0 "/usr/libexec/getty bootupcli" cons25 on secure

If you want vid and comconsol you can edit /boot/loader.conf and add
boot_multicons="YES"
boot_serial="YES"
console="vidconsole,comconsole"
