While I don't understand your post completely, I agree with
your point that udev-compat need not be a high priority as
libeudev meets this need. I understand that without
udev-compat, vdev wouldn't be able to serve some heavyweight
desktop environments.

I think that's okay, because Probably most potential users
of vdev will be using a lightweight window manager or even
just console. I think serving that group will be a good
place to start.

Also, while a database for fast startup would be great,
enabling it to work at all would be a good first step.

Eventually some sort of write-up about vdev comparing it to
mdev, udev, eudev might help getting the word out. (I'd
help with that.)

Thanks for all your work!

Joel
