And experimental's ifupdown can actually work with freebsd native tools so there might be need for some idea on how to transition but it should be not too hard.
Does experimental's ifupdown work with both current wrapper (/sbin/route) and freebsd native tool (/lib/freebsd/route) ? Given it works, we could wait for it's upload into sid, and ship in /sbin/route native one and add Breaks on previous versions. Petr
