Not aware of documentation. Mkdev would be a good start for google. To toggle at boottime, use different runlevels. 1 that mounts tmpfs over /dev and starts udev. Another that doesn't. And /dev contains static device nodes. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
