Roy -

Thanks for testing!  I'm still able to reproduce the issue, stock raspbian
jessie lite works vs. raspbian stretch lite doesn't... in each case with
option vium-env lines added to dhcpcd.conf



$ dhcpcd -V4 | grep vium
239 vium-env                                     string

$ dhcpcd -U4 eth0 | grep vium
domain_name='vium.com'
< no vium-env >
