How can I have no DUMPDEV on a 3B15?

Hi folks,
We have a 3B15 and we want *no* dump device -- how do we do
this? /etc/system lets us specify the swap and dump partitions
with:
DUMPDEV:/dev/dsk/0s1
SWAPDEV:/dev/dsk/0s1 160992 20000
DUMPDEV is required to lie on a partition boundary, but this
isn't required for SWAPDEV. We prefer to put swap at the end of
a partition because to do otherwise means that partition can't
be used for a filesystem, and 45MB (the smallest partition) is
a pretty BMF swap area -- much larger than we need.
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.
Anybody have any ideas? Hotline really had no idea what
I was talking about. We're running Sys V Release 3.1.1,
and these IDFC drives have no VTOC (fixed partition offsets).
Thanks much,
Steve
