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!
