/etc/sysconfig/network/config:CHECK_DUPLICATE_IP="yes". See my comment in bugzilla too.
The current default is no which is wrong. At least for openSUSE and the desktop we must consider to change this.
Considered and rejected: # Also be aware that this takes one second per interface; consider that when # setting up a lot of interfaces.
The world talks about booting faster, not longer
a) A system with a lot of interfaces is very likely not a desktop system where booting fast is the most important goal of the world(tm).
A usual desktop system will have a cable and wireless interface.
b) Apple does it with Mac OS X and if they do it it must be the right approach.
c) Checking for duplicate IP usage costs approximately 1 second.
And the check is very likely only required if the interface is not in autoconfiguration/ DHCP mode.
d) Aren't we executing the init scripts in parallel?
The world talks about usable systems. Better: The world expects a working network configuration and doesn't talk about it. Our users don't even like to think about this case. It just has to work.
