I.e. if you got a WIDE SCSI chip and thus support for 15 targets, there are a total of 120 LUNs on all possible targets. And it takes some 100 bytes per /possible/ LUN (or a total of some 10KB to 15KB if MAX_LUN=8). I'm going to change this (it is not too hard, actually), but for lack of spare time it will have to wait ... Since 10KB are some $0.30 worth of DRAM, I could just make 8 LUNs the default now ...
