500 points EXCELLENT
If you want to control the swap creation during kickstart you could also opt for a "scripted" way.
Define a %pre section in the kickstart file containing following:

%pre #!/bin/sh mem=$((`grep MemTotal: /proc/meminfo | sed ‘s/^MemTotal: *//’|sed ‘s/ .*//’` / 1024)) echo “logvol swap –fstype swap –name=LogVol01 –vgname=VolGroup00 –size=$mem” > /tmp/setswap 1:2:3:4:
Then set the %include around the part where you create the partitions:
Fyi, I've tested the code on a Centos.

You need some swap like gigabyte to have indication when you run out of memory
And you can resize swap logical volume with LVM if your system really goes into crashing.

Did you try using the "recommended" option?
as in:
as in:
According to the docs: The minimum size of the automatically-generated swap partition is no smaller than the amount of RAM in the system and no larger than twice the amount of RAM in the system.
If you want more control you'll need to create something I think ...
