I usually get coffee instead of staring at the laptop. But I wonder how big a difference a smarter disk-elevator algorithm would make. Or something that logged file-accesses, made a list of disk-block-no of that, sorted the list, and early at next boot read of blocks from that list. This is to avoid boot-time being spent waiting for random disk-accesses.
