Do we have a way to identify the prefix(es) in question for the ruleset?
IOW, do the userspace daemons replace the existing prefix or adds a new
one and removes the old one?

The kernel itself seems to make sure the autoconfigured local address
is always the first one on the interface. If userspace does the same
this should be pretty easy.
