Comment 2 for bug 1838221

OK, in the cloud-init source, this is in the description of a property in an example OVF in our documentation. We can fix this to point elsewhere, but I don't think it's a priority for us.

For cloud-images, this string is present in https://git.launchpad.net/livecd-rootfs/tree/live-build/ubuntu-cpc/hooks.d/base/ovf/ubuntu-ovf-v1-img.tmpl (and maybe elsewhere, but definitely at least there).
