# One role-owned netplan file replaces cloud-init's render: eth0 always,
# wifi when enabled. cloud-init only re-renders on a new instance_id, so
# the deletion below sticks across reboots.
#
# RESCUE a dark pi: on the card's FAT partition, edit network-config (a
# phone hotspot entry works) and bump instance_id in meta-data, then
# boot. The re-rendered 50-cloud-init.yaml sorts after 40-net.yaml and
# overrides it; the next playbook run deletes it again.
