Network boot autoconfiguration sets default server to next server IP (siaddr) from BOOTP/DHCP reply, but manual configuration using net_bootp exports only server name. Unfortunately semantic of server name is not clearly defined. BOOTP RFC 951 defines it only for client request, and DHCP RFC 1541 only mentions it, without any implied usage. It looks like this field is mostly empty in server replies. Export next server IP as net_<interface>_next_server variable. This allows grub configuration script to set $root/$prefix based on information obtained by net_bootp. Reported and tested by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com> Cc: nikunj@linux.vnet.ibm.com v2: change variable name to net_<interface>_next_server as discussed on the list
