sysconfig.py fails to configure network

[Ben Howard]

Cloud-init sysconfig.py does not render the subnet configuration properly when the datasource provides a network configruation.

This can be seen on OpenSUSE LEAP 42 and the upcoming Fedora 25.

Hi,
I suspect this is on digital ocean.

Could you please attach the metadata that was sent to the instance?

The full content in /var/log/cloud-init.log would be good as well.

Hi, Ben?
Can you provide this?
