Subject: [PATCH] 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.
