For historical reasons (I guess). You can only boot from the *first* BSD slice on a disk, so the slice number of the root partition is irrelevant (the only root partition you can use is the one on the first BSD slice). This is from times when BSD didn't know about slices. Nadav > > -Sean > ---------------------------------------------------------------------- > Sean J.
