I can't quite trace where the EACCES is coming from, I can't see any obvious causes there - the blacklist key type doesn't have an ->update operation, and the assoc_array insert doesn't look like it would fail. However: if I delete one of the duplicate keys using the bios UI, then the number of errors logged decreases by one. Cheers, Jeremy
