In mys system there is a file called /etc/dumpsave which is a shell
script that asks the question.  You can simply comment out the
call to that function so that the prompt neve apears and things go on
as usual.

However, I found theis homemade hack quite nice for those times
when you *DO* want to save the dump from the swap space durring
development.  It is "obvious" shell programming.

timeout () {
	sleep $1
	echo "Timeout!"
	kill $2
}

# Setup Prompt Timeout Deamon
	trap 'exit 0' 15
	timeout 30 $$ &
	ALARMPROC=$!

echo 'There may be a system dump memory image in the swap device.'
while :
do
	echo 'Do you want to save it? (y/n)> \c'
	read ans
	case $ans in
	  y )   break ;;
	  n )   kill ${ALARMPROC} ; exit 0 ;;
	esac
	echo '???'
done

# Kill Timeout Deamon If Continue
	kill ${ALARMPROC}
	trap 15

The original code only echo(ed) the questions and while(ed) the
answer loop looking for good responses.  In the sense that
AT&T might guess that some of the original bits were from the
distribution file, they may narf at me, but it is identical
to what I would have written for the same loop.  The entire
timeout process thingy and the associated killings (8-)
are mine and you may use them to your harts content.  As many
rights reserved as I can get away with, so if you use it
for yourself feel free, but if it shows up in an offical distribution
I expect cash!

Shame we don't always get what we expect.
