From 2cb55077e2f65f17dbc8933eec47760bcc2a6ba1 Mon Sep 17 00:00:00 2001
From: Eric Andersen <andersen@codepoet.org>
Date: Fri, 10 Dec 1999 08:25:07 +0000
Subject: Added poweroff (and adjusted init to use it).  Inlined function calls
 to code only called once in tee.  Made BB_KLOGD and option.  -Erik
