Am I right that your concern is that the default behavior of a FreeBSD kernel is potentially wondering SCSI disks, and that providing the capability of wiring down the disks is only a partial solution, since the majority of the great unwashed won't wire them down and will be likely to be hurt by this? If we built a kernel using your table above my disks would move around. Also, my tapes will show up as st2 and st3 since they aren't at those targets. I can't see how to change this without having a big upgrade headache and incompatability with existing kernels. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
