A while ago I was seeing messages indicating that -current had trouble
with ipfilter and INET6.  I didn't notice anything saying this was
fixed, but could well have missed it.  Is this currently ok on the
netbsd-2-0 branch?

Is the netbsd-2-0 branch currently in good shape?  (I am running an
earlier version of -current, so 'good shape' is relative to that, not
migrating servers from netbsd-1-6.)  Any big issues?
