Not being very familiar with vdev, I can't tell you what this means beyond
that something didn't get copied or ended up in the wrong place.

This sounds like what I ran into with mdev.
https://github.com/idunham/mdev/blob/master/hooks/mdev-hook, last two lines:
# Apparently, this somehow only gets copied if udev is installed.
copy_modules_dir kernel/drivers/scsi

The directory where that is would probably be helpful for integration
with initramfs-tools; it's what I worked out for making mdev replace
udev.
