Can't disable docker.socket with Ignition

[bgilbert]

With this Ignition config:

{
  "ignition": {
    "version": "3.0.0"
  },
  "systemd": {
    "units": [
      {
        "enabled": false,
        "name": "docker.socket"
      }
    ]
  }
}

I get:

[core@localhost ~]$ rpm-ostree status
State: idle

It's not immediately obvious why the preset isn't being respected. Using Ignition to enable a service does work.

Not ideal, but this gets rid of docker.service and docker.socket (by overwriting the service file) :

systemd:
  units:
    - name: docker.service
      enabled: false
      contents: |
        [Unit]
        Description=disable docker

        [Service]

        [Install]
        WantedBy=multi-user.target

[core@localhost system-connections]$ systemctl status docker.socket

seems like this might be the same thing as #392 except this is a socket and that is a service.

@EnigmaCurry I think an easier way may be to just mask docker.service:

variant: fcos
version: 1.0.0
systemd:
  units:
    - name: docker.service
      mask: true

The fix for this went into testing stream release 36.20220522.2.1 and stable stream release 36.20220522.3.0.
