Comment 10 for bug 1885527

Yes, I do think this is unreasonable.

It is definitely not Hetzner's task to fix Ubuntu.

Especially since that process of re-initiialization of that instance ID is neither obvious nor documented.

Looking at

https://cloudinit.readthedocs.io/

I did not yet find an explanation of what is going on, and at

https://cloudinit.readthedocs.io/en/latest/topics/instancedata.html

it just says

v1.instance_id

Unique instance_id allocated by the cloud.

Examples output:

    i-<hash>

but does not give a hint that this is to be constantly provided by some internal service.

On the contrary, it says

"Cloud-init is the industry standard multi-distribution method for cross-platform cloud instance initialization. It is supported across all major public cloud providers, provisioning systems for private cloud infrastructure, and bare-metal installations."

It says „instance initalization”. It does not say that is keeps modifying the living instance.

So this is undocumented behaviour, and I am more and more thinking about the question, whether this is a backdoor.
