I just tried ntp 4.2.4 which has code to scan for new interface every 5 minutes. That will bind to eth0 sometime after eth0 is brought up.
There is another problem with ntp starting before eth0 is up. When the server lines in ntp.conf use hostnames they can not be resolved. So if ntp does eventually bind to eth0 it still won't work. -- ntp starts before the network is up in feisty https://launchpad.net/bugs/90267 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
