As asked by chiluk on IRC, here's my PXE boot configuration (well, representative one anyway, the exact kernel version will obviously change):
DEFAULT ubuntu LABEL ubuntu LINUX vmlinuz-4.4.0-36-generic APPEND initrd=initrd.img-4.4.0-36-generic root=/dev/nfs nfsroot=10.17.76.1:/var/lib/tribble/ephemeral ip=dhcp ro nomodeset net.ifnames=0 IPAPPEND 2
