That's all but if you disable it, it means that basically any host can
overwrite any record and multiple hosts with the same name will
continuously take turn to update the same record.
With "update-conflict-detection" on, the first host get to update the
zone and after that any other hosts with the same name are rejected as
long as the lease of the first one is valid.
