As you pointed out changing MAXNS would cause an ABI break. The proposal you pointed out looks like a good way to do the change, but it needs to be done upstream in order to keep a compatible ABI between all distributions. In the meantime using a local resolver like unbound is the best workaround. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net
