Verification-done for zesty, with klibc-utils 2.0.4-8ubuntu4.1:
I updated klibc-utils and libklic; then modified the initramfs scripts/functions to add "maybe-break networking" to the end of configure_networking(); and rebooted with 'ip=dhcp break=networking'. I could then verify the contents of /run/net-ens3.conf from the initramfs environment; which checks out: DOMAINSEARCH shows the right value for this network: "nat", same as DNSDOMAIN.
