Yep - udev requires sysfs. But I didn't suggest using udev - however it would work (i.e. create ubd nodes) however for a recent enough kernel. > uml-test has /sys directory but not mounted as sysfs. I don't know how to > mount it as sysfs. This is the etc/fstab for uml-test: See your distro policy - possibly it must be in /etc/fstab, but I don't know. > # This file is edited by fstab-sync - see 'man fstab-sync' for details > /dev/ubd/0 / ext2 defaults 1 1 > /proc /proc proc defaults > devpts /dev/pts devpts mode=0622 0 0 > /dev/ubd/1 none swap sw However, note that /dev/ubd/0, /dev/ubd/1 are not valid when DevFS is not used. Not at all. You must change them if you want to switch away from DevFS. > If udev can't create all device nodes but no devfs mounted, then device > nodes can't be created Why statically creating them beforehand is not an option?

Why is that? Either they have the device nodes (/dev/ubdXX) or they use udev (I know Debian3.0 doesn't) or they do mount none /dev -t devfs (most likely on Debian). -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
