Great majority probably have 1 or 2 disks, so this isn't a big risk for them, but it is also irrelevant to them whether the disks are wired or mapped (most people probably have root disk as id 0 anyway). For large systems it is both administrative trouble and filesystem/database corruption risk. 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. It will continue to cause headache as long as it stays there, and the later the reverting to fixed ids is pushed, the more difficult it will become. - Heikki Suonsivu, T{ysikuu 10 C 83/02210 Espoo/FINLAND, hsu@cs.hut.fi home +358-0-8031121 work -4513377 fax -4555276 riippu SN
