Configuring WiFi via Cloud-Config

This example is valid with Alpine.

#cloud-config

hostname: metal-{{ trunc 4 .MachineID }}
users:
  - name: kairos
    # Change to your pass here
    passwd: kairos
    ssh_authorized_keys:
    # Replace with your github user and un-comment the line below:
    # - github:mudler

stages:
  initramfs:
    - name: Setup wireless
      files:
        # Generate manually by following https://wiki.archlinux.org/title/ConnMan and add contents below
        - path: /var/lib/connman/wifi_xxxxxxxxxxxx_zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz_managed_psk/settings
          permissions: 0600
          content: |
            [wifi_xxxxxxxxxxxx_zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz_managed_psk]
            Name=Your_SSID
            ...etc...
  boot:
    - name: Enable wireless
      commands:
        - connmanctl enable wifi

This example is valid with openSUSE on a Raspberry Pi.
