Why? Why not put it in ROM with your kernel image, look at how the kernel build process does it with the "built-in" initramfs. If that doesn't work, initrd still works just as well for udev, that's what RH does. > I hope someone will pick-up your nano defvs proposal and enhance it to > support a version enabling to boot a system without anything in /dev. I boot my boxes with nothing in /dev and have been for almost a year now. udev works just fine for this, and so do some other programs that work like udev does. I hope everyone can just forget about my nano devfs proposal, and just pass it off as a example of someone who went temporarily insane. thanks, greg k-h
