    4 === Host identification ===
    5   Not all systems have an application-readable globally unique IDs, so we use a different approach to host identification. When a host first contacts the scheduling server it is assigned a host ID. The server also maintains an RPC sequence number for each host. Both the host Id and the RPC sequence number are stored in the client's `client_state.xml` file.

    76If the scheduling server receives an RPC with a sequence number less than the expected sequence number, it creates a new host record in the database. (This might happen, for example, if a user copies the `client_state.xml` file between hosts.)

    10 === Merging duplicate host records ===
    11  This mechanism can lead to situations where the server has multiple host records for a single host. For example, this will occur if the user deletes the `client_state.xml` file.
