# NOTES:
# `--admin-username` and `--generate-ssh-keys` are required by the az cli,
# but are not actually used by talos
# `--os-disk-size-gb` is the backing disk for Kubernetes and any workload containers
# `--boot-diagnostics-storage` is to enable console output which may be necessary
# for troubleshooting
