    Signing-state records are used internally by :iscman:`named` to track
    the current state of a zone-signing process, i.e., whether it is
    still active or has been completed. The records can be inspected
-   using the command :option:`rndc signing -list zone <rndc signing>`. Once :iscman:`named` has
-   finished signing a zone with a particular key, the signing-state
-   record associated with that key can be removed from the zone by
