I'm not sure it helps you, but I've made a vdev variant of most recent
devuan_jessie_RC_amd64_minimal_live.iso (time stamped 2017-Mar-27 20:57)
that I got from the official mirror
http://mirror.sfo12.us.leaseweb.net/devuan/

I purged a couple of things from it, then added and installed "my"
vdev_0.1.1_amd64.deb, and made a refractasnapshot of this, into
devuan_jessie_RC_amd64_minimal_live_vdev.iso, which is downloadable at
https://www.uk.realsam.co.uk/files/devuan/

It boots with vdev rather than udev, and udev remains installed, though
with all its "competing" files tucked away. As you might know, this vdev
packaging is different from aitor's packaging for gnuinos by not
declaring a udev competition, but rather attempting to manage a dynamic
choice of which one is in use. The software is otherwise the same, I
believe.
