allow variables in config patches

e.g. we could have used machine name as machine's hostname

alternatively, this could be just a feature enabled in the spec

That would be perfect!

If I understand it right, there is no way as of now to get the machine name from CAPI and set it on the Talos node(s)?

[smira]

well, that depends on the infrastructure provider in general - e.g. on AWS VM name will match Machine name, but hostname will be different (driven by AWS cloud controller logic).

on bare-metal (with Sidero) there's no way to push machine name down to the host.

I'm currently on CAPV (vSphere). Sorry, forgot to mention that one

Not sure if that's following Talos approach but I'll leave it here for a reference.
CAPI kubeadm bootstrap: https://cluster-api.sigs.k8s.io/tasks/kubeadm-bootstrap.html
Cloud-init config-data is used to deliver the hostname of the Machine and it can be used with a mixture of shell commands to set the hostname, etc.

Is that something that should go into the Platform config - https://github.com/talos-systems/talos/blob/release-0.13/internal/app/machined/pkg/runtime/v1alpha1/platform/vmware/vmware_amd64.go ?
