(i.e. newfs the hard disk, dd to tape, maybe then > mount the tape?) HP used to do install tapes like this too. They had a block tape device which worked on 9-track tape devices. I guess they counted record marks to determine what block they were on and then issues FSR and BSR commands to the drive to position the tape. I suspect they also laid files out on the tape in the order in which the install program was going to use them. I don't know whether the UFS file layout algorithms help or hinder a filesystem on a sequential device.... :-) Martin
