Usually builds are done in multi-user mode as a mild stress test. 

What I'd like to do is avoid my error of a few days ago, in which dtb changed
and a normal buildworld, buildkernel, installworld, installkernel cycle ended
with an unbootable system. Adding a line to the build script to do the
/boot/dtb/rpi2.dtb to /boot/msdos copy looks like one solution. Given that
it's taken 70 builds to fall in this trap I'm a little worried it'll cause
more trouble than it solves. 

Is there any prospect of usb keyboard support in single user? That would simplify
blunder recovery a great deal.

Thanks for reading, and all your help!
