Not commenting on the diff or the feature, which could indeed be the
corect solution, if maybe only to work around some strict/broken servers.
I was under the impression that if you added an "request" statement
excluding the 'domain-name-servers' option the server would honour that and
only offer the options you've explictly requested..
Does something like this work for you?
interface "em0" {
request subnet-mask, broadcast-address, routers, domain-name-servers;
}
interface "em1" {
request subnet-mask, broadcast-address, routers;
}
