there's no guarantee that we're locked here and it also produces unnecessary extra IO in most cases. While at it also avoid that a special:cloudinit section is added on start to *every* VM, which caused another bug to trigger (see prev. commit) and is just odd for users that ain't using cloudinit Note in two call sites that we may need to write the config indeed out there on the caller side.
