Actually, the root partition does start at sector 0. With a sun disk
label, it's always on sector 0, and usually overlaps with the first
partition. Thus, the filesystem is supposed to not occupy the first
sector of its partition, which is the same for how PCs work (the first
sector is usually called the 'boot sector' in PC land; in Sun land, the
partition table/disk label and 'boot sector' can overlap, as there is
no 'master' boot sector for the disk (ala the PC's MBR), thanks to the
intelligence of the Sun's boot prom).
