### Repro Steps

`service docker start`

### Expected Behavior

I'd expect `service docker start` to run without error.

### Actual Behavior

`service docker start` gives this error:

```
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.
```

### Diagnostic Logs

Here's the output of `systemctl status docker.service`:

```

If I have this in my `/etc/wsl.conf` file `service docker start` doesn't work:

```
[boot]
systemd=true
```
If I comment out the `systemd=true` bit `service docker start` works but not with that line in place.

Reproduce `service docker start` on WSL 2 with `[boot] systemd=true` in `/etc/wsl.conf`, then compare `systemctl status docker.service` and `journalctl -xeu docker.service` with the configuration where systemd is disabled. Done means Docker starts successfully while systemd is enabled, or the incompatibility is documented with a clear diagnostic.
