There are situations where linux's old behavior is useful.
Example situation: While setting up a test machine at a university, I was given an unassigned IP. Somebody had happened to be using the IP though. Both machines were NT, so they throw up a little message box telling you about the IP conflict. The user whom had taken the IP, just kept clicking Ok, without reading the error. After quite a few minutes of this, I brought up a linux machine with the offending IP. In about 2 minutes, a call came into the helpdesk reporting the error.
So linux's current behavior as far as duplicate IPs, can be handy. If this new behavior, can be turned off via /proc, defaulting to catching duplicates is not a bad thing. Maybe /proc/sys/net/ipv4/ip_conflict?
