How to create a custom slackware "live" dvd?

I usually use a slackware-15 setup DVD as "livecd". Is more fast than other real live cd and contain a ssh daemon. When I use it as livecd I did those steps step1: give an easy root password echo -e'password\npassword\n' |passwd root step2: start networking dhcpcd -q -4 eth0 step3: start dropbear (ssh) /etc/rc.d/rc.dropbear start my question is: is possible to create a custom iso of 15.0 which make automatically those 3 steps? How to start?
