Thank you Daniel for your pointers. I am a kubernetes newbie so wanted to 
clarify in order to more fully understand your answer:

1) "we're fixing this": does it mean some "cos-stable-6*" release will run 
this again as cos-stable-58 was, or would I need to make some edits 
(kubernetes config vars etc.) in the cloud init file? I have some 
automation relying on that and for now forcing "cos-stable-58-...", would 
like to have a heads up on what to expect from the future VM image releases.

2) "updating /etc/default/kubelet": how can I include that in cloud init 
yaml file?

Also, while we're on this topic, could you please have a look at a related 
disk mounting issue here:
https://stackoverflow.com/questions/44222208/standalone-kubelet-persistent-disk-mount-on-google-cloud-instance

Thank you!
Pavel
