I'm about to run my own simple cluster. I want my nodes runs the operating system off the network (netboot) since they don't have any hard-drive to store the operating system. (Btw, my interest is Ubuntu). I have seted up a perfect DHCP server - netboot server and tftp and works perfect. As a test I have booted up all the nodes using Ubuntu LiveCD !!!!!
Everything is fine so far, but here is my question: Since I want these nodes for parallel programming, I have to have pre-installed applications that I have wrote. Ubuntu's LiveCD doesn't have those (neither any other liveCD linux distro).
Can I make my own Ubuntu image that is bootable and has installed my configuration? if yest, how can I do that?
