thought so. so all that tom needs to do is assign the nodename following this logic, however he will also need to test whether that device is a Direct-Acces or not. this can be done using the same wizardry i already use in scsiinfo(). (parsing /proc/scsi/scsi) it would make ofpath slower on devfs systems, but thats the price you pay for using devfs ;-) > and so on.
