scsi target to a disk unit for setroot(). If anyone knows a better way to do this, please let me know. The only other way I could think of would be to add a field in disk.h:struct dkdevice to reference the scsi target. Ideally, the correct boot device would be passed in from the booter. As we only have one scsi bus (until we support NuBUS scsi cards), it makes sense to be backward-compatible (especially since mac weenies seem to need help tying their shoes).
