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 “idle” 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 “idle” system set, while the first “active” system set remains operational. The utility node device may comprise a smart utility meter, sensor, control device, transformer, switch, relay, or the like.
