+Subject: [PATCH] Handle CNAME and DNAME in resume_min in a special way
+
+When authoritative zone is loaded when query minimization query for the
+same zone is already pending, it might receive unexpected result codes.
+
+Normally DNS_R_CNAME would follow to query_cname after processing sent
+events, but dns_view_findzonecut does not fill CNAME target into
+event->foundevent. Usual lookup via query_lookup would always have that
+filled.
+
+Ideally we would restart the query with unmodified search name, if
+unexpected change from recursing to local zone cut were detected. Until
+dns_view_findzonecut is modified to export zone/cache source of the cut,
+at least fail queries which went into unexpected state.
