I guess the best way of doing that is via kickstart
I was thinking about yum... you could do
yum list installed | tail -n +4 | awk '{ print $1 }'
but still there is some work to do.
Maybe "rpm -qa" is a better way to have the list, but still, if you have to
install multiple systems at once, I guess that kickstarting is the best way.
