Good point. We need to maintain human-distinguishability of the different SCSI device types, so under /dev/scsi should be things like /dev/scsi/disk-sOmEtHiNg, /dev/scsi/tape-sOmEtHiNg, etc. I agree that making directories for *everything* would get out of control. The top-level directory should be reserved for names that more-or-less match the old-style names, for backwards compatibility. Of course, if you're running an all-devfs system, then you could turn the old-style names off with a config option and use only the /dev/scsi/blah names. This improves performance somewhat for those massive disk farmers. --Scott @ @ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-oOO-(_)-OOo-=-=-=-=-= C.
