Code review comment for ~bitfehler/cloud-init:bitfehler/load_seed

"if the nocloud-net does render the "new" network config even though the network is already up then that's fine."

Its *not* fine. network datasources should not render network information at this point. Doing so will only confuse things and create a system that "maybe works". We cannot really ensure that it will work, and we're not going to support if it didn't.

So just make it simpler, and only read network config in the local.
