Why couldn't it use this info (pass it on to userland) in other (non-diskless)
cases?  Linux domU's can do it, and it looks like a useful feature to me (e.g.
sending a generic domU image to your Xen hosting provider without having to
worry about the network configuration; they would simply provide it in the Xen
config file and your NetBSD domU would use that info).
