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."
