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.
