For many years "root=LABEL=/" has been the anaconda default for kernel
commandline parameter, (at least when not using LVM.)
This was motivated by the possible renumbering of [SCSI] drives
even when _adding_ a new good drive.  There still are grub.conf
stanza lines such as
   splashimage=(hd0,0)/grub/splash.xpm.gz
and
        root (hd1,0)
which do name physical partitions [frequently not whole physical drives.]
