It reflects the state of the kernel, which decides what to do autonomously based on a number of driver and platform-dependent things including, but not limited to, kenv (loader variables, for instance). I was thinking it, but didn't express it properly... yes... kern.console is influenced by loader variables. "slurped" is definitely not the technical explanation I should be striving for ;D (that is, if I'm trying to be clear). -- Devin _____________ The information contained in this message is proprietary and/or confidential.
