This can of course (and frequently is) implemented in userspace, but requires an initrd. I'm not up to speed how scsi_wait_scan is put to use --- it can be used without initrd, can't it? > I know that new devices really can show up at any > time, but I think it's reasonable to say that if a machine is booted > with the same configuration as last time, the drives should show up with > the same names. I know that is not what you meant here, but...: They do show up with the same target identifiers and logical unit identifiers. The SCSI core doesn't pass the identifiers through to userland though.
