fetch-glue
This option is obsolete. In BIND 8, fetch-glue yes caused the server to attempt to fetch glue resource records it didn't have when constructing the additional data section of a response. This is now considered a bad idea and BIND 9 never does it.
Fixed in [1003].

Je proposes qu'on utilise la modifications de O.H. (cfr http://alternc.org/marchives/dev/2006-March/002151.html) qui permet (si j'ai bien tout compris) à la fois de fermer le serveur DNS récursif ouvert par rapport à l'extérieur et de le rendre utilisable en local.

non, il ne faut pas mélanger les serveurs récursifs et non-récursifs:

Si vous voulez faire cette erreur, /etc/alternc/templates et pour vous. :)
