These two are traditionally a source of real problems for devfs or arrangements like it. I had an Irix system once where I wanted to be sure disks attached to the external scsi connectors -- used only for a tape drive -- couldn't be used. What a pain that was. Yet the internal disk slots were fully populated and I knew what device names they'd attach as. It should have been the easiest thing in the world to just not keep device nodes around for any other disks. Instead, I got a day-long odessey of struggle with SGI's udevd-like setup and its magic startup scripts... it shouldn't be that hard. In fact, it shouldn't be hard at all! Thor
