It is just that I prefer to have a new installations
completely isolated from previous ones, with the
installation not writing to the MBR and following blocks ie /dev/sda.
The only reason is in case things go wrong - when installing
F9T1 say.

As it happens, in the example I gave, I put the whole installation
in one partition /dev/sda6 (/ and /boot) complete with the
"secondary" grub written at the front ie /dev/sda6
F8 picks up an existing swap partition.

If required I can over write /dev/sda6 with something else without
touching /dev/sda.

Whether its desirable that F8 should be booted from an F8 version of grub
rather than an older version I don't know, but this approach avoids that possibility.

The assume the story must be completely different if using LVM and/or RAID.
