Currently, cloud-init can run into issues applying network configuration if the MAC addresses reported by the system are in a different case to the MAC addresses provided by the network configuration source. It is likely that there are also other places where a mismatch could happen. We should ensure that cloud-init's MAC address handling is not case sensitive.
[Original Report]
I'm using an ISO with the following yaml in network-config. cloud-init will not match eth0, but will match eth1 due to capitalization.
version: 2 ethernets: eth0: match: macaddress: 00:15:5D:0E:AE:0C set-name: External eth1: match: macaddress: 00:15:5d:0e:ae:0d set-name: Internal
RuntimeError: Not all expected physical devices present: {'00:15:5D:0E:AE:0C'}
cloudinit/net/init.py, Line 545, in wait_for_physdevs.
Can you either fix the documentation to explicitly require lower case (this page has several uppe case references: https://cloudinit.readthedocs.io/en/latest/topics/network-config-format-v2.html). Or do the lower case conversion in wait_for_physdevs when you compare the present_macs to the expected_macs?

Hi,
Thanks for the bug report! I've filed bug 1876941 specifically for the documentation changes you suggested, and I'm going to rework this bug report slightly to cover fixing the underlying problem.

Since we've updated the docs to accurately specify and show examples of lowercase, I'm demoting the importance of dealing with the rest of this.
