dig @server foobar +trace +recurse

[Anne Bennett]

I've been trying to debug a problem with dig, and it has finally
occurred to me that, if I understand this correctly, the "+trace"
option essentially overrides the @server specification, except for
the initial query for the root zone nameservers.  (I was using
"+showsearch +trace +recurse".)

Is my understanding correct?

If it is, it might be helpful to add a quick note to the "dig"
manpage, perhaps under "SIMPLE USAGE", "server", something like:

  Note that if when the +trace and +recurse options are in
  use, only the initial query for the root zone uses the
  server specified by "server" (or in /etc/resolv.conf);
  subsequent queries use the authoritative servers in the
  chain of delegation.
