Public bug reported:
Looking at the source code of cloud-init, when it tries to read a
network configuration file, it looks for MAC address. Looking at the
source code, it gives an impression that MAC address is a requirement to
rename interfaces.
However, looking at this documentation,
https://cloudinit.readthedocs.io/en/latest/topics/network-config-
format-v2.html , it mentions that if I want to rename a network
interface, I can use either name, macaddress or driver.
This is the most misleading part because, firstly, the source code does NOT search through 'name' and uses 'device_id' instead, whereas the documentation says:
"name: <(scalar)>
Current interface name. Globs are supported, and the primary use case
for matching on names, as selecting one fixed name can be more easily
achieved with having no match: at all and just using the ID (see above).
Note that currently only networkd supports globbing, NetworkManager does
not."
