In article <256 at mrstve.UUCP> rjk at mrstve.UUCP (Richard Kuhns) replies:

I've never used a 3b2, so I'm taking Richard's word for it that the
only way to power-down the machine is via a software command. I'm sorry,
but if this is really true, then that machine has some serious brain-damage
to it. Hell, my Vax has software shutdown, but when the system die{ it's
nice to know I can still hit that reset button or turn the key-switch to
"off". Comes in handy when smoke starts to curl out of the disk drive too.
On the other side of the coin, I wouldn't want some software bug to
be able to power-down my system by mistake -- I know my disk drives are
designed for that, but I still sleep better if I spin then down before
turning off the power. Unix may still need a lot of improvements, but
/dev/powerswitch isn't one of them.
