The way powerdns handles records is quite simple, and in a sense, the
domain_id is bit misleading.
All names in 'records' table are assumed to be fully qualified, they are
not filled in from domains table, thus if you have empty name in records
table, it does indeed mean 'root zone'.
The domains table is used to figure out what zones you have but when
responding, the system trusts whatever you have in records table.
