Overview

Carries the cloud-init network-config for the advanced-network private NIC into a NoCloud cidata seed. The ISO build is delegated to the :create_iso host capability and the attach goes through the provider disk capability (cap/disk.rb).

NoCloud reads user-data, meta-data and network-config from a single filesystem labelled “cidata”; two cidata volumes are ambiguous. So when core CloudInitSetup (which runs earlier in the chain) has already built a user-data seed, we rebuild that same ISO in place with network-config added instead of attaching a second seed.
