systemd in xenial-proposed has support for predictable network interfaces names for ACPI-described platform devices. However, the latest d-i in xenial-proposed was built with the previous systemd upload. This has a nasty side-effect that the NICs will have have different names during install (e.g. eth1) but after reboot, will have a different name (e.g. enahisic1). Further, if you used one of these NICs as your install interface, the network will fail to come up post-install.
