hello -

i see these in my `error.log` for installs, too.  on reboot, however,
these hosts are successfully booting with systemd's "predictably named"
interface managed via `/etc/network/interfaces.d` (ubuntu 16.04 / fai
5.9.4)

if you want to transition to the systemd naming scheme, i would suggest
starting by looking in your config space, particularly
`scripts/DEBIAN/30-interface` as it compares to https://raw.githubuserc
ontent.com/faiproject/fai-config/master/scripts/DEBIAN/30-interface. 
if you have updated the fai packages but not examined upstream's fai-
config scripts/hooks/etc. you may find the solution there.

if you want to avoid the systemd interface naming, some solutions that
could be implemented can be found at https://www.debian.org/releases/st
able/amd64/release-notes/ch-information.en.html#migrate-interface-names
