Public bug reported:

Seen with cloud-init-18.2-3.13.x86_64 from SLES 15 Public-Cloud-
Module_15-0.

This is important:

2018-10-31 13:57:37,530 - stages.py[DEBUG]: not a new instance. network
config is not applied.


Both are marked a debug. So currently I default to use "grep -v util.py" when looking at cloud init logs to retain my own sanity. I think it is possible to make it easier than this for admins to use cloud-init. Especially as when compared to 0.7.9 cloud-init has seem to become way more complex and more difficult to understand.
