Thanks for the explanation mika. I was hoping that I can just backup those
static devices, but I found both my /dev/.static/dev/ & /lib/udev/devices/
are empty. If I duplicate null, zero, console and tty[0-9] devices into
/dev/.static/dev/ and back them up, would it works?

Yeah, 1MB is not that big. My worry was the portability. If I backup all
devices in PC A, then restore them on PC B, what would happen?

Thanks
