I just tested this package and it instantly solved all my networking problems.
Thank you!

I've been struggling with the network intermittently not coming up, and thus
being unable to contact the metadata service of my cloud, resulting in a dead
instance. I've tried everything from systemd drop-ins to creating a
/etc/NetworkManager/NetworkManager.conf to convince cloud-init to look at the
sysconfig renderer, to no avail. This newer cloud-init package is the answer.
