Nope. Our interactive OS determination machine is still running
4.3-STABLE, as is the uptime determination machine.

Setting RANDOM_IP_ID would definitely have an effect on OS determination
- a random IP ID is _one_ of the factors used in differentiating between
OpenBSD and the other *BSDs.
We've not looked in detail as to why FreeBSD-4.6+ systems are coming up
as unknown (not all of them are), but as we run FreeBSD here, it's a
fairly safe bet that FreeBSD determination will continue into the
foreseeable future...
(PS, if anyone knows what changes there are in the 4.6+ networking code,
please let us know - it'd definitely speed up getting this fixed...)
