It could be argued that people who use bootp+extension >path should be encouraged to migrate to DHCP. Actually on further thought I think it should still be backward compatible as a bootp server will ignore the parameters (and lack of some options) in a DHCPDISCOVER message and send the extension file path anyway. |
