In one embodiment, a device in a network receives update recovery data from a neighbor of the device in the network. The device monitors the neighbor during installation of a software update by the neighbor. The device detects an installation failure of the software update by the neighbor. The device causes recovery of the neighbor using the update recovery data, in response to detecting the installation failure of the software update by the neighbor.

In one embodiment, a computing system identifies one or more terminal nodes in a digraph, and then back-walks primitives up the digraph from each terminal node to a corresponding parent terminal node or a root of the digraph, whichever is first. The system then identifies chains of back-walked primitives for each of the one or more terminal nodes (e.g., where each chain consists of a respective terminal node and any primitives either a) up to but not including a corresponding parent terminal node or else b) up to and including the root of the digraph when the back-walking reaches the root). Based on this, the system can then merge each set of any two or more chains of the identified chains that intersect on a decision operation into a corresponding new single chain, and maps each of the chains to a respective rule.
