Comment 20 for bug 1835205

Thinking a bit outside the box maybe

would getting the instance-id from the machine, just like vmware-guestinfo datasource, a better idea?

https://github.com/vmware/cloud-init-vmware-guestinfo/blob/99442e7ab784561c116caae54fe3a0c4a947a207/DataSourceVMwareGuestInfo.py#L160-L167

fudging around with a random instance id to recustomize a machine sounds like the wrong way around.
