If the VM is completely dependent on systemd-resolved for name
resolution, then I think the problem might be that vmdebootstrap,
despite its name, does not actually do anything with VMs. Instead,
it runs as root and does everything with chroot(), including running
the setup script - so at the time the setup script runs,
systemd-resolved.service is not available, because services aren't
run while chrooted?
