Yes, it certainly makes sense to me. One problem is explaining it to
customers. What I _dont_ understand is the different behavior. If more
sites were running the same rev of BIND that FreeBSD does now, then the
offending site would fix the issue. i.e. why does LINUX and its sendmail
and BIND work when FreeBSD and its BIND do not... Or why is LINUX 'broken'
and FreeBSD being more 'correct'.
