freebsd-dev/sys/boot/forth/menu-commands.4th
Devin Teske a3ed1123db Discussed at-length on -arch.
Make the following interface changes to my beastie boot menu:
+ Move boot options to a submenu
+ Add a new "Boot Single" menu item
+ Make "Boot" item and new "Boot Single" item reverse when boot_single is set
+ Add new "Load Defaults" item (in new "Boot Options" submenu) for overridding
  loader.conf(5) provided values with system defaults.
