I've had the hints file fail on my server multiple times since I've been running my servers... DNS breaks and I get a constast stream of messages that have no relationship to a failure to contact a root server... The first time it happened it took me close to a day to find out that a simple refresh of my hints file fixed the problem... Now, when I see that message, I now know to update my hints file, but it isn't very good to require manual updating of the hints file every few years to stave off broken dns. So, mark on up to supporting a dns based distribution of the root... (Not necessarily using the existing root servers, but some method that will ensure that dns will not break just because it does.) -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
