takeoverzx takeover RealmName
This command notifies the local ZX/Zomp node that it is the "prime" node for the given realm and places the realm on the "managed" realms list in the local configuration. In this mode the local node will not try to locate or contact any other nodes for index updates regarding this realm and will enlist connecting realms as mirrors if they enroll for updates from the given realm.
Note, however, that taking over a realm for which you do not have the sysop keys will fail in the case downstream nodes connect to you, as history entry and package signatures will not match.
