When I looked at the code again, I realized there is one reason to want to be able to set it to zero which is that the check is now applied to boot time (in init_scsi_delay()) so is you set SCSI_DELAY=3D0 you get SCSI_DELAY=3DSCSI_MIN_DELAY even if if you compile it in. Given you example above, maybe we should just remove the checks entierly since in the current configuration you would have 14.4sec of delay (not hugh, but perhaps undesirably large). My comment about footshooting was refering to removing the attempt to keep people from trying to set the value in seconds, not that you were doing it to yourself. I'm fully aware you know more about scsi them I'm, ever likely to. :) -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
