First, let's instead change read_metadata_ec2() to return a Result<Option<MetadataEc2JSON>>. So then it would return Ok(None) in this case. It should only return that if the error was ENOENT. Grep the codebase for NotFound for examples of this.
Second, this is a lot of metadata we're not injecting now. Are you sure that information is not available in the openstack/meta_data.json? I was under the impression when we talked about this that it was.

All the metadata we are not injecting seems to be either ec2 related (INSTANCE_ID, INSTANCE_TYPE), or somewhat irrelevant, at least in my use case: IPV4_LOCAL and IPV4_PUBLIC .
The information provided by metal3 is the following:
{
"local-hostname": "bmh-vm-02",
"local_hostname": "bmh-vm-02",
"metal3-name": "bmh-vm-02",
"metal3-namespace": "test-capi",
"name": "bmh-vm-02",
"uuid": "30aed4c7-05a4-4d15-be9b-9194dc1b5ad1"
}
We can see uuid, hostname - although none of its label it's matching the current provider's key - and other metal3 related keys (useful to build the providerID pattern expected by metal3).

Instead of the match, you can .map(Some) to wrap it in an Option.

You can do something like:
let Some(...) = self...()? else {
return Ok(out);
};

On baremetal platform, when reading metadata from a configdrive with openstack layout we get the following error:
This PR ignores ec2 metadata if not present:
