## the long version
we start a DHCP server on the storagenode that provides PXE boot information (TFTP protocol) to each diskless node. The information is stored on the storagenode as well. The boot information then boots a linux kernel and ramfs. The root filesystem is accessed by the kernel via NFS and is also stored on the storagenode for each individual diskless computenode. DHCP, TFTP and NFS need to be installed and configured. IPTABLES needs new rules to allow DHCP, TFTP and NFS to pass through the firewall.
