I agree we should make this part more clean. In fact it is location where to
install grub2 stage1. So I am still fighting what is precise but user friendly
label.

Well, it is possible, but problem is that we use udev names to prevent change
of kernel names, so often device is
/dev/disk/by-uuid/a47f29fe-de47-4976-bc54-4dfd30a0cb47 which is too long for
this part.

ok, in fact this section of documentation is wrong as it changed for Leap 42.2
and TW. Now MBR use disk MBR where "/boot" lives. so if "/boot" is on
/dev/sdb6, then it install grub2 to /dev/sdb.
Also boot from root is not default. Default proposal is very complex code that
consider partitioning setup. So currently default is pick between root/boot
partition and MBR depending on disk setup.

For help to user which option use when it is not so easy. In general if
opensuse is only system on disk, then MBR is always good option. If there are
more systems and that system can chainload ( almost majority of current OSes ),
then boot from partition is good idea unless it use specific partitioning
scenarios ( it is quite long list including encrypted partitions, RAIDs and
more. I will need more digging if you want exact list when what can be used).
