When I did a single-user mode boot to install a new world, I saw the
following warning on the (serial) console during boot:

   /boot.config: -D -S115200
   Consoles: internal video/keyboard  serial port
   BIOS drive A: is disk0
   BIOS drive C: is disk1
   BIOS 638kB/3143616kB available memory

   FreeBSD/x86 bootstrap loader, Revision 1.1

   Loading /boot/defaults/loader.conf
   /boot/kernel/kernel data=0xb73530 data=0x11dbe0+0x2b4db8 syms=[0x8+0xfd620+0x8+0xec6b6]
   Hit [Enter] to boot immediately, or any other key for command prompt.

   Type '?' for a list of commands, 'help' for more detailed help.
   OK boot -s
   menu-unset not found           <<-- what's this?
   GDB: no debug ports present
   KDB: debugger backends: ddb
   KDB: current backend: ddb
   [...kernel boots...]

E.g, it always gives a 'menu-unset not found' warning (or maybe it's an
error, it's not clear).  This was not the case before r228985.

I have almost no knowledge about forth, but it looks like this might be
caused by the new try-menu-unset subroutine.

My loader.conf is just this:

   console="comconsole vidconsole"
