Amit, May I suggest PXE Boot? (This is of course due to the lecture I gave in this issue on Haifux :) http://haifux.org/lectures/114/ (Slides should be available soon, I already sent them to Orna). Using Network loaded boot can allow you to manage several boot images, and switch them quite simply (just reboot the machine). IMHO this solution is much simpler than custom flash booting mechanisms, easy installation, no special hardware required, centralized control etc. All the boot images are located in one server, all the clients in the cluster boot by pulling the appropriate boot image by TFTP and DHCP. With fancy DHCP configuration I can imagine you can even change the configuration in the server, so every machine in the cluster boots from a specific boot image (via MAC address DHCP or alike). Hope this was helpful...
