You can reach the problem with IPv4 if you have a very special setup (several
IP for one interface that are not always setup at the same time, ...).
You reach the problem with IPv6 even with common setup (ie an IPv4 and an
IPv6 address with a few classic feature such as bridge, ...)

Martin F. Krafft started to implement a replacement of ifupdown that
is better designed. But, due to lack of manpower I think, this project
did not finish. See this archives of netconf-devel@lists.alioth.debian.org
for more info.
