On my linux system, I lost /dev during a disk change because of running devfs (mounted on /dev) and therefore not being able to copy the underlying /dev. This made me unable to boot a non-devfs kernel, as it was not able to open /dev/console. Neither could I fix the underlying /dev, as there were open files in the devfs which stopped me from unmounting it. Multiple mounts to the rescue: I mounted the root fs once more under itself on /mnt, so that hde5 was both / and /mnt. Then I could mknod, MAKEDEV and whatnot in /mnt/dev. For normal system usage, I'm not sure if multiple mounts are that useful, though... Oystein -- ssh -c rot13 otherhost
