I preferred the idea of mounting it _over_ /dev, or at least not using the
same semantics as the current unionfs, as /dev may be mounted on a
filesystem that is:
- not capable of whiteouts
- not capable of device nodes
I'd _really_ like to see some kind of layer that can "translate" regular
files into device nodes somehow ... for the purposes of a NFS /dev. Real
device nodes on a NFS-mounted /dev are, as said before, dangerous and a
serious security risk.
