True, you can't always reboot to single user (and that is dangerous, but
often unavoidable), but you can "make kernel" (or make buildkernel &&
make installkernel) which is the only officially supported way of
building a kernel. The way you did it usually works, but is not
officially supported and may fail in some cases.
