Not really. If recursion is off for your name server, it isn't going
to query other name servers and so won't have any need to fetch glue
records. Unless you've done something really wacky like disable
recursion but enable forwarding....

Nope. The keyword here is FETCH. Just because a name server doesn't
fetch glue from other name servers doesn't mean it can't hand out glue
records.

Yup.

    Christine> So naturally, fetch-glue no follows recursion no, correct?

Sort of. If recursion is off, there should be no need to fetch glue
and so it won't matter whether fetch-glue is set to yes or no. Your
name server won't need to go looking for glue when recursion is off.
