#     We have a 3B15 and we want *no* dump device -- how do we do

#        DUMPDEV:/dev/dsk/0s1

#     DUMPDEV is required to lie on a partition boundary, but this

I think (!) I read that you can't move the primary swap device.
The reason they let you specify anything is so you can set
up MORE swap devices.

#     We had a very unfortunate experience some time ago where a
#misspecified DUMPDEV ate our /usr filesystem, and we would very
#much like to avoid this in the future.  I suppose I can
#repartition the machine to make a dump partition, but it seems
#like such a waste when I want to just ignore it.

The kernel will dump whenever it thinks it's in trouble.
I'm not sure if you can make it NOT do this.  That would
mean something is going to get written over.

# Hotline really had no idea what I was talking about.
 
THAT'S scary.
