jbjohnso ae2bece3ec -Have discovery refuse to give the same IP address to multiple nics by default
-Have nbroot explicitly try to send packets out of each up interface
-Prevent empty /etc/motd warnings
-Fix issue where discovery failed with classic MM
-Change check for network sameness to a live check instead of table check in nodediscover
-Have nbroot quiet by default to alleviate conserver log usage
-Have dhcp plugin mac deletion be a bit more aggressive, delete matching mac addresses
-Have discovery disable DHCP offers for multiple NICs on the same network if nothing resembling a proper guess can be made
