It would be useful to have possibility of changing dhcp (bootp) ports from 67/68 to (for example) 1067/1068. Option could be named --dhcp-port=...., or --alternate-dhcp-port (for 1067/1068).
It is necessary when we have another dhcp server(s) in out network, but not providing all information needed to boot a workstation. Etherboot bootroms propose those alternate ports. I can prepare a patch if You would like me to do so (for my use I only changed it in config.h). -- Jan Psota
