A system set of a utility node device, such as a kernel and/or root file system, may be updated by utilizing a multi-system set configuration. For example, the multi-system set configuration may include a first system set that is generally configured to act as an 'active' set, a second system set (e.g., 'idle' set) that is configured to operate when the first system set is non-operational or in an &#x201c;idle&#x201d; state, and a third system set that is configured to operate when the first and second system sets are non-operational. During an update of a system set, an update package may be applied to the second &#x201c;idle&#x201d; system set, while the first &#x201c;active&#x201d; system set remains operational. The utility node device may comprise a smart utility meter, sensor, control device, transformer, switch, relay, or the like.

Utilizing a multi-system set configuration to update a utility node system set

The techniques described herein implement an operating system that can reliably process time sensitive information in non real-time manner. Thus, the operating system described herein is capable of processing an instance of time sensitive input during a time period after the instance of time sensitive input is received (e.g., at a future point in time). To accomplish this, the techniques timestamp each instance of time sensitive input when it is received at a device. The techniques then store the timestamped instance of time sensitive input in a temporary queue, and make the timestamped instance available to the operating system at a time period after the time period when it is received, as indicated by the timestamp. Additional techniques described herein prioritize the activation of a driver configured to receive the time sensitive information during a boot sequence or a reboot sequence.

Non real-time metrology data management

Software and/or firmware of a utility node device may be updated by utilizing an update package that includes multiple update items related to different types of the software and/or firmware. The utility node device may selectively install one or more of the multiple update items based on a type of the software and/or firmware that is currently installed on the device. The different types of software and/or firmware may relate to different versions of the software and/or firmware and/or different types of hardware. In some instances, an update item of the update package comprises a delta file that contains differences between different versions of the software and/or firmware. The utility node device may comprise a smart utility meter, sensor, control device, transformer, switch, relay, or the like.
