Verify that the device's factory-default configuration boots cleanly and that the device remains usable afterwards -- i.e. it does not fall back to the fail-secure failure-config. The test exercises the device's own first-boot bootstrap path: it clears the startup-config and reboots with the test-mode startup override set, so confd initialises running from the factory-config (its first-boot path). That mirrors a factory-fresh / factory-reset device and avoids applying a full config swap over the live management session -- confd cannot replace the whole running datastore from within an RPC without timing out, and a factory config may reconfigure the very transport we are connected over. The test is image-generic, using whatever factory-config the running image was built with, so it covers both the stock Infix factory config and any spin factory config. A single-node (1x1) topology is used on purpose: a factory config is not written with a lab full of peers in mind, so booting it across a multi-node topology could trigger broadcast storms or similar. NETCONF only, as it is the one management transport present in every factory config.

Description
Verify that the device’s factory-default configuration boots cleanly and that the device remains usable afterwards. I.e. it does not fall back to the fail-secure failure-config.
This exercises the device’s own first-boot bootstrap path: with no startup-config present, confd initialises running from the factory-config. That is exactly what a factory-fresh (or factory-reset) device does, and it avoids applying a full config swap over the live management session.
The test is image-generic: it uses whatever factory-config the running image was built with, so it covers both the stock Infix factory config and any spin factory config.
A single-node topology is used on purpose: a factory config is not written with a lab full of peers in mind, so applying it across a multi-node topology could trigger broadcast storms or similar.
