Other disks can easily >be opened in /etc/rc using something `disklabel </dev/rdk0 >/dev/null'. Oops, they seem to be broken now for a non-root devfs. The partitions on my zip disk /dev/sd1 aren't created when /dev/sd1 is looked at in various ways, and unmounting devfs hangs all disk i/o after a while. (At first only the unmount process seemed to be hung - ps was able to run and should the process hanging on vgone. Now ps in ddb show that many processes are hanging on ufslk2. I thought that this problem was fixed.) Bruce
