- Subject: [PATCH 1/1] idbw_rec_write, pick tpgt from existing record
-
- On a static add (-m node -o new) without a user specified tpgt, looks
- for existing new style records with tpgt before creating an old style
- record without. If one exists, take the tpgt from it an write an
- updated new style record instead.
