So please enlighten us poor souls who have *no*idea* why you'd need to "clean out" /dev when moving to an udev-based system. Why not leave the old package-supplying-/dev-nodes installed?
You can mount a tempfs onto /mnt/whatever, create the bare essential device nodes there, move-mount that to /dev, and start up udev. (In fact, this is how a udev-based system boots in the first place.)
Total downtime for programs attempting to open /dev/null (or whatever): Zero.
Afterwards, if you do want to remove the old /dev-supplying package, well ... RPM has a --justdb option.
