This rather huge change is a refactor of the factory-config generataion to add support for also generating a failure-config. The confd bootstrap script has been given an rc file. This both eases manual testing, when modifying the script(s), and also makes it easier to override from a br2-external. Infix default is router/end-device, but a br2-external may be a switch firmware and want to default to all ports in a bridge. The generated failure-config creates a fail-safe "do no harm" config to boot with in case startup-config for some reason is broken or cannot be applied, e.g., bug in confd. Meaning, for both the router and switch use-cases the device will start up with all interfaces isolated¹, with an IPv6 SLAAC (EUI64) address per interface. Services enabled in this fail-safe mode are: LLDP, mDNS/SD, SSH, and NETCONF. All to facilitate diagnostics, troubleshooting and device recovery. Other noteworthy changes include: - rename factory/failure directories again -> factory.d/failure.d. Use same naming as we do on target for directories holding generated files - The bootstrap script no longer regenerates /cfg/factory.d on each boot - The bootstrap script copies all static templates to /cfg/factory.d in case a newer image changes the contents of them. For troubleshooting - Support for overriding the 20-interfaces.json generation by br2-external - Support for additional 30-config.json (ovrride/extend) by br2-external - Expand gen-interfaces to support bridge use-case. _____ ¹ For a switch this means "no switchport", i.e., no switching between ports otherwise connected to a switchcore (or bridge) in startup-config.
