Yes, I'm glad you asked.  That particular use case will go away with
giant initrd.  Unfortunately for preupgrade, it will might be replaced
by a harder to solve problem (see bug#646843) when 500M /boot doesn't
have enough space.

Thanks.  I think this behavior has been there for some time.  I've
typically just rebooted and adjusted my arguments, or updated the ks.cfg
to use the correct NIC.  But I think with the patch, it will avoid
having to reboot and allow the user to select a different device or IP
