# ifupdown can't glob iface stanzas (no mapping on ifupdown2/Proxmox), so ENI binds
# a literal name detected here. The chroot only sees live-ISO names: on a real
# ifupdown base, set system.network.interfaces[].name to the installed name. Bootstrap
# installs NetworkManager, so this fires only on a non-NM base image.
