IMHO that would fix udev nicely. I've been considering creating a fs based on tmpfs that does just that for udev, if only to keep issues like this from coming up all the time :) > Is trapfs suitable for that? trapfs looks to be based on ramfs, not tmpfs, so I don't think it would work out as well. But Adam might have a different idea. thanks, greg k-h
