The abstract at the top of David Malone's paper says: Tests, described here, indicate that this technique seems to be comparable to the traditional hints mechanism for moderately busy name servers and may offer other benefits Indeed the paper, various messages in dns-operations and so forth would seem to suggest this is more of use for busier systems with hundreds if not thousands of users. These installs are probably something of a minority, and more to the point are more likely to have had a reasonable amount of time and research spent poking at configs. Many more smaller installs are probably going to be thrown up by people with less interest in such; "Oh, I just want a resolver and some local DNS names for my 2 user home network/10 user business, I guess the default config will be fine". I would suggest that the commented bits be reversed; have a hints file as the default, more traditional, less controversial option, with slave zones commented out, with a more explicit note about when and why it might be helpful, and mentioning any caveats re smaller installs, less root server support, Paul Vixie kicking puppies, etc. Even if slave zones are generally better, I would still think the more conservative approach would be the better one, especially in 6.*. -- Thomas 'Freaky' Hurst http://hur.st/
