single-user mode

[Dru]

It's been a while since I've had to enter single-user mode and I've just
discovered that "boot -s" doesn't work at the "boot" prompt on 5.1-RELEASE.
(however, it does work nicely if I interrupt loader at the next boot
stage).

In fact, I can't get *anything* to work at the "boot" prompt, or even
leave that prompt without doing a CTRL ALT DEL. Am I missing something, or is
the "boot" prompt defunct on 5.x?
